ChangeLog for Privoxy
--------------------------------------------------------------------
-*** Version 3.0.30 UNRELEASED ***
+*** Version 3.0.33 stable ***
+- Security/Reliability:
+ - cgi_error_no_template(): Encode the template name to prevent
+ XSS (cross-site scripting) when Privoxy is configured to servce
+ the user-manual itself.
+ Commit 0e668e9409c. OVE-20211102-0001. CVE-2021-44543.
+ Reported by: Artem Ivanov
+ - get_url_spec_param(): Free memory of compiled pattern spec
+ before bailing.
+ Reported by Joshua Rogers (Opera) who also provided the fix.
+ Commit 652b4b7cb0. OVE-20211201-0003. CVE-2021-44540.
+ - process_encrypted_request_headers(): Free header memory when
+ failing to get the request destination.
+ Reported by Joshua Rogers (Opera) who also provided the fix.
+ Commit 0509c58045. OVE-20211201-0002. CVE-2021-44541.
+ - send_http_request(): Prevent memory leaks when handling errors
+ Reported by Joshua Rogers (Opera) who also provided the fix.
+ Commit c48d1d6d08. OVE-20211201-0001. CVE-2021-44542.
+
+- Bug fixes:
+ - 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:
+ - 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.
+

+ - 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.'.

+ - 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'.
+

+ - 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:

+ - 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:

+ - 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".
+
+*** Version 3.0.32 stable ***
+
+- Security/Reliability:
+ - ssplit(): Remove an assertion that could be triggered with a
+ crafted CGI request.
+ Commit 2256d7b4d67. OVE-20210203-0001. CVE-2021-20272.
+ Reported by: Joshua Rogers (Opera)
+ - cgi_send_banner(): Overrule invalid image types. Prevents a
+ crash with a crafted CGI request if Privoxy is toggled off.
+ Commit e711c505c48. OVE-20210206-0001. CVE-2021-20273.

+ Commit a912ba7bc9c. OVE-20210205-0001. CVE-2021-20275.
+ Reported by: Joshua Rogers (Opera)
+ - Obsolete pcre: Prevent invalid memory accesses with an invalid
+ pattern passed to pcre_compile(). Note that the obsolete pcre code
+ is scheduled to be removed before the 3.0.33 release. There has been
+ a warning since 2008 already.
+ Commit 28512e5b624. OVE-20210222-0001. CVE-2021-20276.
+ Reported by: Joshua Rogers (Opera)
+
+- Bug fixes:
+ - Properly parse the client-tag-lifetime directive. Previously it was
+ not accepted as an obsolete hash value was being used.
+ Reported by: Joshua Rogers (Opera)
+ - decompress_iob(): Prevent reading of uninitialized data.
+ Reported by: Joshua Rogers (Opera).
+ - decompress_iob(): Don't advance cur past eod when looking
+ for the end of the file name and comment.
+ - decompress_iob(): Cast value to unsigned char before shifting.
+ Prevents a left-shift of a negative value which is undefined behaviour.
+ Reported by: Joshua Rogers (Opera)
+ - gif_deanimate(): Confirm that that we have enough data before doing
+ any work. Fixes a crash when fuzzing with an empty document.
+ Reported by: Joshua Rogers (Opera).
+ - buf_copy(): Fail if there's no data to write or nothing to do.
+ Prevents undefined behaviour "applying zero offset to null pointer".
+ Reported by: Joshua Rogers (Opera)
+ - log_error(): Treat LOG_LEVEL_FATAL as fatal even when --stfu is
+ being used while fuzzing.
+ Reported by: Joshua Rogers (Opera).
+ - Respect DESTDIR when considering whether or not to install
+ config files with ".new" extension.
+ - OpenSSL ssl_store_cert(): Fix two error messages.

+ - fuzz_server_header(): Fix compiler warning.
+ - fuzz_client_header(): Fix compiler warning.
+ - cgi_send_user_manual(): Also reject requests if the user-manual
+ directive specifies a https:// URL. Previously Privoxy would try and
+ fail to open a local file.
+
+- General improvements:
+ - Log the TLS version and the the cipher when debug 2 is enabled.
+ - ssl_send_certificate_error(): Respect HEAD requests by not sending a body.
+ - ssl_send_certificate_error(): End the body with a single new line.
+ - serve(): Increase the chances that the host is logged when closing
+ a server socket.
+ - handle_established_connection(): Add parentheses to clarify an expression
+ Suggested by: David Binderman
+ - continue_https_chat(): Explicitly unset CSP_FLAG_CLIENT_CONNECTION_KEEP_ALIVE
+ if process_encrypted_request() fails. This makes it more obvious that the
+ connection will not be reused. Previously serve() relied on
+ CSP_FLAG_SERVER_CONTENT_LENGTH_SET and CSP_FLAG_CHUNKED being unset.
+ Inspired by a patch from Joshua Rogers (Opera).
+ - decompress_iob(): Add periods to a couple of log messages
+ - Terminate the body of the HTTP snipplets with a single new line
+ instead of "\r\n".
+ - configure: Add --with-assertions option and only enable assertions
+ when it is used
+ - windows build: Use --with-brotli and --with-mbedtls by default and
+ enable dynamic error checking.
+ - gif_deanimate(): Confirm we've got an image before trying to write it
+ Saves a pointless buf_copy() call.
+ - OpenSSL ssl_store_cert(): Remove a superfluous space before the serial number.
+

+ The ungreedy version broke the img tags on:
+ https://bulk.fefe.de/scalability/.
+
+- Privoxy-Log-Parser:
+ - Highlight a few more messages.

+*** Version 3.0.31 stable ***
+
+- Security/Reliability:
+ - Prevent an assertion from getting triggered by a crafted CGI request.

+
+- Bug fixes:
+ - Fixed detection of insufficient data for decompression.
+ Previously Privoxy could try to decompress a partly
+ uninitialized buffer.
+
+*** Version 3.0.30 stable ***
- Bug fixes:
- Check the actual URL for redirects when https inspecting requests.
This unbreaks (at least) https://config.privoxy.org/client-tags whose
buttons would previously use a http:// URL resulting in browser warnings.
- Support using https-inspection and client-header-order at the same time.
- Privously Privoxy would crash.
+ Previously Privoxy would crash.
Reported by: Kai Raven
- Properly reject rewrites from http to https as they currently
aren't supported. Previously Privoxy would wait for the client
to establish an encrypted connection which obviously would not happen.
+ - When https inspection is enabled and Privoxy has been compiled with
+ FEATURE_GRACEFUL_TERMINATION (not recommended for production builds),
+ the TLS backend resources are free'd later on and only if no active
+ connections are left. Prevents crashes when exiting "gracefully" at the
+ wrong time.
+ - Let the uninstall target remove the config file even if DESTDIR
+ is set and properly announce the deletion of the configuration files.
- General improvements:
- - Allow to rewrite the request destination for https-intercepted
+ - Allow to rewrite the request destination for https-inspected
requests behind the client's back. The documentation already sort
of claimed that it was supported by not especially mentioning that
it didn't work for https-inspected requests.
fatal error so the regression tests can be used with and
without FEATURE_PCRE_HOST_PATTERNS.
- The code compiles with older C compilers again.
- - Check the chdir() return code to fix a compiler warning.
- - Let the crude-parental filter insert a link to Privoxy's webinterface.
- - Remove the packages feed from the source tarball.
+ - The chdir() return code is checked to fix a compiler warning.
+ - The packages feed has been removed from the source tarball.
It's usually out of date when the source tarball is generated
for the release.

directory which is no longer used. The images were relocated to
the user-manual directory years ago.
- Add new FEATURES to the show-status page and resort list.
- - OpenSSL create_client_ssl_connection(): Remove unused variable.
+ - Remove unused variable in the OpenSSL-specific code.
- Update bug tracker URL in cgi_error_unknown().

- Improved a couple of error messages.
- Saved memory allocations when using OpenSSL and checking if a
- The configure script will bail out if OpenSSL and mbedTLS are
enabled at the same time.
- Log a message right before exiting gracefully.
+ - A couple of structures have been rearranged to require slightly
+ less memory.
+ - When https inspection is enabled and the certificate is invalid
+ the error message is now sent with status code 403 instead of 200.
+ - The Slackware rc script template has been renamed to
+ slackware/rc.privoxy.in to silence complaints when building
+ Debian packages.
+ - When building with MbedTLS support, mbedtls_md5_ret() is used
+ instead of mbedtls_md5() which is deprecated and causes a warning
+ on Debian GNU/Linux.
