OVE-20211201-0001. CVE-2021-44542. - Bug fixes: - - Client sockets are now properly shutdown and drained before being - closed. This fixes page truncation issues with clients that aggressively - pipeline data on platforms that otherwise discard already written data. - The issue mainly affected Opera users and was initially reported - by Kevin in #3464439, szotsaki provided additional information to track - down the cause. - - Fix latency calculation for shared connections (disabled by default). - It was broken since their introduction in 2009. The calculated latency - for most connections would be 0 in which case the timeout detection - failed to account for the real latency. - - Reject URLs with invalid port. Previously they were parsed incorrectly and - characters between the port number and the first slash were silently - dropped as shown by curl test 187. - - The default-server-timeout and socket-timeout directives accept 0 as - valid value. - - Fix a race condition on Windows that could cause Privoxy to become - unresponsive after toggling it on or off through the taskbar icon. - Reported by Tim H. in #3525694. - - Fix the compilation on Windows when configured without IPv6 support. - - Fix an assertion that could cause debug builds to abort() in case of - socks5 connection failures with "debug 2" enabled. - - Fix an assertion that could cause debug builds to abort() if a filter - contained nul bytes in the replacement text. + - handle_established_connection(): Skip the poll()/select() calls + if TLS data is pending on the server socket. The TLS library may + have already consumed all the data from the server response in + which case poll() and select() will not detect that data is + available to be read. + Fixes SF bug #926 reported by Wen Yue. + - continue_https_chat(): Update csp->server_connection.request_sent + after sending the request to make sure the latency is calculated + correctly. Previously https connections were not reused after + timeout seconds after the first request made on the connection. + - free_pattern_spec(): Don't try to free an invalid pointer + when unloading an action file with a TAG pattern while + Privoxy has been compiled without FEATURE_PCRE_HOST_PATTERNS. + Closes: SF patch request #147. Patch by Maxim Antonov. + - Adjust build_request_line() to create a CONNECT request line when + https-inspecting and forwarding to a HTTP proxy. + Fixes SF bug #925 reported by Wen Yue. + - load_config(): Add a space that was missing in a log message. + - read_http_request_body(): Fix two error messages that used an + incorrect variable. + - If the the response is chunk-encoded, ignore the Content-Length + header sent by the server. + Allows to load https://redmine.lighttpd.net/ with filtering enabled. - General improvements: - - Significantly improved keep-alive support for both client and server - connections. - - New debug log level 65536 which logs all actions that were applied to - the request. - - New directive client-header-order to forward client headers in a - different order than the one in which they arrived. - - New directive tolerate-pipelining to allow client-side pipelining. - If enabled (3.0.20 beta enables it by default), Privoxy will keep - pipelined client requests around to deal with them once the current - request has been served. - - New --config-test option to let Privoxy exit after checking whether or not - the configuration seems valid. The limitations noted in TODO #22 and #23 - still apply. Based on a patch by Ramkumar Chinchani. - - New limit-cookie-lifetime{} action to let cookies expire before the end - of the session. Suggested by Rick Sykes in #1049575. - - Increase the hard-coded maximum number of actions and filter files from - 10 to 30 (each). It doesn't significantly affect Privoxy's memory usage - and recompiling wasn't an option for all Privoxy users that reached the - limit. - - Add support for chunk-encoded client request bodies. Previously - chunk-encoded request bodies weren't guaranteed to be forwarded correctly, - so this can also be considered a bug fix although chunk-encoded request - bodies aren't commonly used in the real world. - - Add support for Tor's optimistic-data SOCKS extension, which can reduce the - latency for requests on newly created connections. Currently only the - headers are sent optimistically and only if the client request has already - been read completely which rules out requests with large bodies. - - After preventing the client from pipelining, don't signal keep-alive - intentions. When looking at the response headers alone, it previously - wasn't obvious from the client's perspective that no additional responses - should be expected. - - Stop considering client sockets tainted after receving a request with body. - It hasn't been necessary for a while now and unnecessarily causes test - failures when using curl's test suite. - - Allow HTTP/1.0 clients to signal interest in keep-alive through the - Proxy-Connection header. While such client are rare in the real world, it - doesn't hurt and couple of curl tests rely on it. - - Only remove duplicated Content-Type headers when filters are enabled. - If they are not it doesn't cause ill effects and the user might not want it. - Downgrade the removal message to LOG_LEVEL_HEADER to clarify that it's not - an error in Privoxy and is unlikely to cause any problems in general. - Anonymously reported in #3599335. - - Set the socket option SO_LINGER for the client socket. - - Move several variable declarations to the beginning of their code block. - It's required when compiling with gcc 2.95 which is still used on some - platforms. Initial patch submitted by Simon South in #3564815. - - Optionally try to sanity-check strptime() results before trusting them. - Broken strptime() implementations have caused problems in the past and - the most recent offender seems to be FreeBSD's libc (standards/173421). - - When filtering is enabled, let Range headers pass if the range starts at - the beginning. This should work around (or at least reduce ) the video - playback issues with various Apple clients as reported by Duc in #3426305. - - Do not confuse a client hanging up with a connection time out. If a client - closes its side of the connection without sending a request line, do not - send the CLIENT_CONNECTION_TIMEOUT_RESPONSE, but report the condition - properly. - - Allow closing curly braces as part of action values as long as they are - escaped. - - On Windows, the logfile is now written before showing the GUI error - message which blocks until the user acknowledges it. - Reported by Adriaan in #3593603. - - Remove an unreasonable parameter limit in the CGI interface. The new - parameter limit depends on the memory available and is currently unlikely - to be reachable, due to other limits in both Privoxy and common clients. - Reported by Andrew on ijbswa-users@. - - Decrease the chances of parse failures after requests with unsupported - methods were sent to the CGI interface. + - Allow to edit the add-header action through the CGI editor by + generalizing the code that got added with the suppress-tag action. + Closes SF patch request #146. Patch by Maxim Antonov. + - Add a CGI handler for /wpad.dat that returns a + Proxy Auto-Configuration (PAC) file. + Among other things, it can be used to instruct clients + through DHCP to use Privoxy as proxy. + For example with the dnsmasq option: + dhcp-option=252,http://config.privoxy.org/wpad.dat + Initial patch by Richard Schneidt. + - Don't log the applied actions in process_encrypted_request() + Log them in continue_https_chat() instead to mirror chat(). + Prevents the applied actions from getting logged twice + for the first request on an https-inspected connection. + - OpenSSL generate_host_certificate(): Use config.privoxy.org as Common Name + Org and Org Unit if the real host name is too long to get accepted by OpenSSL. + Clients should only care about the Subject Alternative Name + anyway and we can continue to use the real host name for it. + Reported by Miles Wen on privoxy-users@. + - Establish the TLS connection with the client earlier and decide + how to route the request afterwards. This allows to change the + forwarding settings based on information from the https-inspected + request, for example the path. + - listen_loop(): When shutting down gracefully, close listening ports + before waiting for the threads to exit. Allows to start a second + Privoxy with the same config file while the first Privoxy is still + running. + - serve(): Close the client socket as well if the server socket + for an inspected connection has been closed. Privoxy currently + can't establish a new server connection when the client socket + is reused and would drop the connection in continue_https_chat() + anyway. + - Don't disable redirect checkers in redirect_url(). + Disable them in handle_established_connection() instead. + Doing it in redirect_url() prevented the +redirect{} and + +fast-redirects{} actions from being logged with LOG_LEVEL_ACTIONS. + - handle_established_connection(): Slightly improve a comment. + - handle_established_connection(): Fix a comment. + - socks5_connect(): Fix indentation. + - handle_established_connection(): Improve an error message. + - create_pattern_spec(): Fix ifdef indentation. + - Fix comment typos. + - process_encrypted_request(): Improve a log message. + The function only processes request headers and there + may still be unread request body data left to process. + - chat(): Log the applied actions before deciding how to forward the request. + - parse_time_header(): Silence a coverity complaint when building without assertions. + - receive_encrypted_request_headers(): Improve a log message. + - mbedTLS get_ciphersuites_from_string(): Use strlcpy() instead of strncpy(). + Previously the terminating NUL wasn't copied which resulted + in a compiler warning. This didn't cause actual problems as + the target buffer was initialized by zalloc_or_die() so the + last byte of the target buffer was NUL already. + Actually copying the terminating NUL seems clearer, though. + - Remove compiler warnings. "log_error(LOG_LEVEL_FATAL, ..." + doesn't return but apparently the compiler doesn't know that. + Get rid of several "this statement may fall through + [-Wimplicit-fallthrough=]" warnings. + - Store the PEM certificate in a dynamically allocated buffer + when https-inspecting. Should prevent errors like: + 2021-03-16 22:36:19.148 7f47bbfff700 Error: X509 PEM cert len 16694 is larger than buffer len 16383 + As a bonus it should slightly reduce the memory usage as most + certificates are smaller than the previously used fixed buffer. + Reported by: Wen Yue + - OpenSSL generate_host_certificate(): Fix two error messsages. + - Improve description of handle_established_connection() + - OpenSSL ssl_store_cert(): Translate EVP_PKEY_EC to a string. + - OpenSSL ssl_store_cert(): Remove pointless variable initialization. + - OpenSSL ssl_store_cert(): Initialize pointer with NULL instead of 0. - Action file improvements: - - Remove the comment that indicated that updated default.action versions - are released on their own. - - Block 'optimize.indieclick.com/' and 'optimized-by.rubiconproject.com/' - - Unblock 'adjamblog.wordpress.com/' and 'adjamblog.files.wordpress.com/'. - Reported by Ryan Farmer in #3496116. - - Unblock '/.*Bugtracker'.

Reported by Angelina Matson. - - Various grammar and spelling corrections - - Add a client-header-tagger{} example for disabling filtering for range - requests. - - Correct a URL in the "Privoxy with Tor" FAQ. - - Spell 'refresh-tags' correctly. Reported by Don in #3571927. - - Sort manpage options alphabetically. - - Remove an incorrect sentence in the toggle section. The toggle state - doesn't affect whether or not the Windows version uses the tray icon. - Reported by Zeno Kugy in #3596395. - - Add new contributors since 3.0.19. - -- Log message improvements: - - When stopping to watch a client socket due to pipelining, additionally log - the socket number. - - Log the client socket and its condition before closing it. This makes it - more obvious that the socket actually gets closed and should help when - diagnosing problems like #3464439. - - In case of SOCKS5 failures, do not explicitly log the server's response. - It hasn't helped so far and the response can already be logged by enabling - "debug 32768" anyway. This reverts v1.81 and the follow-up bug fix v1.84. - - Relocate the connection-accepted message from listen_loop() to serve(). - This way it's printed by the thread that is actually serving the - connection which is nice when grepping for thread ids in log files. - -- Code cleanups: - - Remove compatibility layer for versions prior to 3.0 since it has been - obsolete for more than 10 years now. - - Remove the ijb_isupper() and ijb_tolower() macros from parsers.c since - they aren't used in this file. - - Removed the 'Functions declared include:' comment sections since they tend - to be incomplete, incorrect and out of date and the benefit seems - questionable. - - Various comment grammar and comprehensibility improvements. - - Remove a pointless fflush() call in chat(). Flushing all streams pretty - much all the time for no obvious reason is ridiculous. - - Relocate ijb_isupper()'s definition to project.h and get the ijb_tolower() - definition from there, too. - - Relocate ijb_isdigit()'s definition to project.h. - - Rename ijb_foo macros to privoxy_foo. - - Add malloc_or_die() which will allow to simplify code paths where malloc() - failures don't need to be handled gracefully. - - Add strdup_or_die() which will allow to simplify code paths where strdup() - failures don't need to be handled gracefully. - - Replace strdup() calls with strdup_or_die() calls where it's safe and - simplifies the code. - - Fix white-space around parentheses. - - Add missing white-space behind if's and the following parentheses. - - Unwrap a memcpy() call in resolve_hostname_to_ip(). - - Declare pcrs_get_delimiter()'s delimiters[] static const. - - Various optimisations to remove dead code and merge inefficient code - structures for improved clarity, performance or code compactness. - - Various data type corrections. - - Change visibility of several code segments when compiling without - FEATURE_CONNECTION_KEEP_ALIVE enabled for clarity. - - In pcrs_get_delimiter(), do not use delimiters ouside the ASCII range. - Fixes a clang complaint. - - Fix an error message in get_last_url() nobody is supposed to see. - Reported by Matthew Fischer in #3507301. - - Fix a typo in the no-zlib-support complaint. Patch submitted by Matthew - Fischer in #3507304. - - Shorten ssplit()'s prototype by removing the last two arguments. We always - want to skip empty fields and ignore leading delimiters, so having - parameters for this only complicates the API. - - Use an enum for the type of the action value. - - Rename action_name's member takes_value to value_type as it isn't used as - boolean. - - Turn family mismatches in match_sockaddr() into fatal errors. - - Let enlist_unique_header() verify that the caller didn't pass a header - containing either \r or \n. - - Change the hashes used in load_config() to unsigned int. That's what - hash_string() actually returns and using a potentiallly larger type - is at best useless. - - Use privoxy_tolower() instead of vanilla tolower() with manual casting of - the argument. - - Catch ssplit() failures in parse_cgi_parameters(). + - Disable fast-redirects for .microsoftonline.com/. + - Disable fast-redirects for idp.springer.com/. + - Disable fast-redirects for .zeit.de/zustimmung. + - Unblock adv-archiv.dfn-cert.de/. + - Block requests to eu-tlp01.kameleoon.eu/. + - Block requests to fpa-events.arstechnica.com/. + - Unblock nlnet.nl/. + - Unblock adguard.com/. + +- Privoxy-Log-Parser: + - Highlight 'Socket timeout 3 reached: http://127.0.0.1:20000/no-filter/chunked-content/36'. + - Improve documentation for inactivity-detection mode. + - Detect date changes when looking for inactivity. + - Add a --passed-request-statistics-threshold option + that can be set to get statistics for requests that + were passed. + - Add a "inactivity detection" mode which can be useful + for debugging purposes. + - Bump version to 0.9.4. + - Only run print_intro() and print_outro() when syntax highlighting. + - Rephrase a sentence in the documentation. + - Highlight 'Client socket 7 is no longer usable. The server socket has been closed.'. + - Clarify --statistics output by explicitly mentioning that + the status codes sent by the server may differ from the ones + in "debug 512" messages. + - Fix typo in the --statistics output. + - Remove an unused variable. + - Highlight 'The peer notified us that the connection on socket 11 is going to be closed'. - Privoxy-Regression-Test: - - Add an 'Overwrite condition' directive to skip any matching tests before - it. As it has a global scope, using it is more convenient than clowning - around with the Ignore directive. - - Log to STDOUT instead of STDERR. - - Include the Privoxy version in the output. - - Various grammar and spelling corrections in documentation and code. - - Additional tests for range requests with filtering enabled. - - Tests with mostly invalid range request. - - Add a couple of hide-if-modified-since{} tests with different date formats. - - Cleaned up the format of the regression-tests.action file to match the - format of default.action. - - Remove the "Copyright" line from print_version(). When using --help, every - line of screen space matters and thus shouldn't be wasted on things the - user doesn't care about. + - Remove duplicated word in a comment. -- Privoxy-Log-Parser: - - Improve the --statistics performance by skipping sanity checks for input - that shouldn't affect the results anyway. Add a --strict-checks option - that enables some of the checks again, just in case anybody cares. - - The distribution of client requests per connection is included in - the --statistic output. - - The --accept-unknown-messages option has been removed and the behavior - is now the default. - - Accept and (mostly) highlight new log messages introduced with - Privoxy 3.0.20. +- regression-tests.action: + - Add fetch test for http://p.p/wpad.dat. + - Bump for-privoxy-version to 3.0.33 which introduced the wpad.dat support. + - Add more tests for the '/send-banner' code. + - Add test for OVE-20210203-0001. + - Add a test for CVE-2021-20217. - uagen: - - Bump generated Firefox version to 17. - -- GNUmakefile improvements: - - The dok-tidy target no longer taints documents with a tidy-mark - - Change RA_MODE from 0664 to 0644. Suggested by Markus Dittrich in - #3505445. - - Remove tidy's clean flag as it changes the scope of attributes. - Link-specific colors end up being applied to all text. Reported by Adam - Piggott in #3569551. - - Leave it up to the user whether or not smart tags are inserted. - - Let w3m itself do the line wrapping for the config file. It works better - than fmt as it can honour pre tags causing less unintentional line breaks. - - Ditch a pointless '-r' passed to rm to delete files. - - The config-file target now requires less manual intervention and updates - the original config. - - Change WDUMP to generate ASCII. Add WDUMP_UTF8 to allow UTF-8 in the - AUTHORS file so the names are right. - - Stop pretending that lynx and links are supported for the documentation. - -- configure improvements: - - On Haiku, do not pass -lpthread to the compiler. Haiku's pthreads - implementation is contained in its system library, libroot, so no - additional library needs to be searched. - Patch submitted by Simon South in #3564815. - - Additional Haiku-specific improvements. Disable checks intended for - multi-user systems as Haiku is presently single-user. Group Haiku-specific - settings in their own section, following the pattern for Solaris, OS/2 and - AmigaOS. Add additional library-related settings to remove the need for - providing configure with custom LDFLAGS. - Submitted by Simon South in #3574538. + - Bump generated Firefox version to 91 (ESR). + - Bump version to 1.2.3. + - Bump copyright. + +- Build system: + - configure: Bump SOURCE_DATE_EPOCH. + - GNUmakefile.in: Fix typo. + - configure: Add another warning in case --disable-pthread + is used while POSIX threads are available. + Various features don't even compile when not using threads. + - Add configure option to enable MemorySanitizer. + - Add configure option to enable UndefinedBehaviorSanitizer. + - Add configure option to enable AddressSanitizer. + - Bump copyright. + - Add a configure option to disable pcre JIT compilation. + While JIT compilation makes filtering faster it can + cause false-positive valgrind complaints. + As reported by Gwyn Ciesla in SF bug 924 it also can + cause problems when the SELinux policy does not grant + Privoxy "execmem" privileges. + - configure: Remove obsolete RPM_BASE check. + +- Windows build system: + - Update the build script to use mbed tls version 2.6.11. + - Update build script to use the final 8.45 pcre library. + - Put all the '--enable-xxx' options in the configure call together. + +- macOS build system: + - The OSXPackageBuilder repository has been updated and + can be used to create macOS packages again. + +- Documentation: + - contacting: Remove obsolete reference to announce.sgml. + - contacting: Request that the browser cache is cleared before + producing a log file for submission. + - Sponsor FAQ: Note that Privoxy users may follow sponsor links + without Referer header set. + - newfeatures: Clarify that https inspection also allows to + filter https responses. + - developer-manual: Mention that announce.txt should be updated + when doing a release. + - config: Explicitly mention that the CGI pages disclosing the + ca-password can be blocked and upgrade the disclosure paragraphs + to a warning. + - Put all the requested debug options in the config file. + Section 11.1 of the Privoxy user manual lists all the debug + options that should be enabled when reporting problems or requesting support. + Make it easier for users to do the right thing by having all those + options present in the config. + - Update TODO list item #184 to note that WolfSSL support will + (hopefully) appear after the 3.0.34 release. + - Update max-client-connections's description. + On modern systems other than Windows Privoxy should + use poll() in which case the FD_SETSIZE value isn't + releveant. + - Add a warning that the socket-timeout does not apply + to operations done by TLS libraries. + - Make documentation slightly less "offensive" for some people + by avoiding the word "hell". ----------------------------------------------------------------- About Privoxy: @@ -321,73 +237,70 @@ networks.
