+ Announcing Privoxy 3.0.23 stable
--------------------------------------------------------------------
-This is a bug-fix release for Privoxy 3.0.20 beta. It also addresses
-a security issue that affects all previous Privoxy versions (on some
-platforms).
+Privoxy 3.0.23 stable is a bug-fix release, some of the fixed bugs
+are security issues (CVE requests pending):
--------------------------------------------------------------------
ChangeLog for Privoxy
--------------------------------------------------------------------
-*** Version 3.0.21 stable ***
+*** Version 3.0.23 stable ***
- Bug fixes:
- - On POSIX-like platforms, network sockets with file descriptor
- values above FD_SETSIZE are properly rejected. Previously they
- could cause memory corruption in configurations that allowed
- the limit to be reached.
- - Compiles on OS/2 again now that unistd.h is only included
- on platforms that have it.
+ - Fixed a DoS issue in case of client requests with incorrect
+ chunk-encoded body. When compiled with assertions enabled
+ (the default) they could previously cause Privoxy to abort().
+ Reported by Matthew Daley.
+ - Fixed multiple segmentation faults and memory leaks in the
+ pcrs code. This fix also increases the chances that an invalid
+ pcrs command is rejected as such. Previously some invalid commands
+ would be loaded without error. Note that Privoxy's pcrs sources
+ (action and filter files) are considered trustworthy input and
+ should not be writable by untrusted third-parties.
+ - Fixed an 'invalid read' bug which could at least theoretically
+ cause Privoxy to crash. So far, no crashes have been observed.
+ - Compiles with --disable-force again. Reported by Kay Raven.
+ - Client requests with body that can't be delivered no longer
+ cause pipelined requests behind them to be rejected as invalid.
+ Reported by Basil Hussain.
- General improvements:
- - The show-status page shows the FEATURE_STRPTIME_SANITY_CHECKS status.
- - A couple of assert()s that could theoretically dereference
- NULL pointers in debug builds have been relocated.
- - Added an LSB info block to the generic start script.
- Based on a patch from Natxo Asenjo.
- - The max-client-connections default has been changed to 128
- which should be more than enough for most setups.
+ - If a pcrs command is rejected as invalid, Privoxy now logs
+ the cause of the problem as text. Previously the pcrs error
+ code was logged.
+ - The tests are less likely to cause false positives.
- Action file improvements:
- - Block rover.ebay./ar.*\&adtype= instead of "/.*\&adtype=" which
- caused too man false positives.
- Reported by u302320 in #360284, additional feedback from Adam Piggott.
- - Unblock '.advrider.com/' and '/.*ADVrider'.
- Anonymously reported in #3603636.
-
-- Filter file improvements:
- - Added an iframes filter.
-
-- Documentation improvements:
- - The whole GPLv2 text is included in the user manual now,
- so Privoxy can serve it itself and the user can read it
- without having to wade through GPLv3 ads first.
- - Properly numbered and underlined a couple of section titles
- in the config that where previously overlooked due to a flaw
- in the conversion script. Reported by Ralf Jungblut.
- - Improved the support instruction to hopefully make it harder to
- unintentionally provide insufficient information when requesting
- support. Previously it wasn't obvious that the information we need
- in bug reports is usually also required in support requests.
- - Removed documentation about packages that haven't been provided
- in years.
-
-- Privoxy-Regression-Test:
- - Only log the test number when not running in verbose mode
- The position of the test is rarely relevant and it previously
- wasn't exactly obvious which one of the numbers was useful to
- repeat the test with --test-number.
-
-- GNUmakefile improvements:
- - Factor generate-config-file out of config-file to make testing
- more convenient.
- - The clean target now also takes care of patch leftovers.
-
-*** Version 3.0.20 beta ***
-
-- 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.
-
-- 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 receiving 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.
-
-- 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 pwhk in #3522341.
- - Add test URLs for '.freebsd.org' and '.watson.org'.
- - Unblock '.urbandictionary.com/popular'.
- - Block '.adnxs.com/'.
- - Block 'farm.plista.com/widgetdata.php'.
- - Block 'rotation.linuxnewmedia.com/'.
- - Block 'reklamy.sfd.pl/'. Reported by kacperdominik in #3399948.

- - Disable fast-redirects for '.googleapis.com/'.
- - Block 'imp.double.net/'. Reported by David Bo in #3070411.
- - Block 'gm-link.com/' which is used for email tracking.
- Reported by David Bo in #1812733.
- - Verify that requests to "bwp." are blocked. URL taken from #1736879
- submitted by Francois Marier.
- - Block '/.*bannerid='. Reported by Adam Piggott in #2975779.
- - Block 'cltomedia.info/delivery/' and '.adexprt.com/'.
- Anonymously reported in #2965254.
- - Block 'de17a.com/'. Reported by David Bo in #3061472.

- - Block '/scripts/webtrends\.js'. Reported by johnd16 in #3002729.
- - Block requests for 'pool.*.adhese.com/'. Reported by johnd16 in #3002716.
- - Update path pattern for Coremetrics and add tests.
- Pattern and URLs submitted by Adam Piggott #3168443.
- - Enable +fast-redirects{check-decoded-url} for 'tr.anp.se/'.
- Reported by David Bo in #3268832.
- - Unblock '.conrad.se/newsletter/banners/'. Reported by David Bo in #3413824.
- - Block '.tynt.com/'. Reported by Dan Stahlke in #3421767.
- - Unblock '.bbci.co.uk/radio/'. Reported by Adam Piggott in #3569603.
- - Block requests to 'service.maxymiser.net/'.
- Reported by johnd16 in #3118401 (with a previous URL).
- - Disable fast-redirects for Google's "let's pretend your computer is
- infected" page.
- - Unblock '/.*download' to resolve actionsfile feedback #3498129.
- Submitted by Steven Kolins (soundcloud.com not working).
- - Unblock '.wlxrs.com/' which is required by hotmail.com.
- Fixes #3413827 submitted by David Bo.
- - Add two unblock patterns for popup radio and TV players.
- Submitted by Adam Piggott in #3596089.
-
-- Filter file improvements & bug fixes:
- - Add a referer tagger.
- - Reduce the likelihood that the google filter messes up HTML-generating
- JavaScript. Reported by Zeno Kugy in #3520260.
+ - '.sify.com/' is no longer blocked. Apparently it is not actually
+ a pure tracking site (anymore?). Reported by Andrew on ijbswa-users@.
+ - Unblock banners on .amnesty.de/ which aren't ads.
- Documentation improvements:
- - Revised all OS X sections due to new packaging module (OSXPackageBuilder).
- - Update the list of supported operating systems to clarify that all Windows
- versions after 95 are expected to work and note that the platform-specific
- code for AmigaOS and QNX currently isn't maintained.
- - Update 'Signals' section, the only explicitly handled signals are SIGINT,
- SIGTERM and SIGHUP.
- - Add Haiku to the list of operating systems on which Privoxy is known to
- run.
- - Add DragonFly to the list of BSDs on which Privoxy is known to run.
- - Removed references to redhat-specific documentation set since it no longer
- exists.
- - Removed references to building PDFs since we no longer do so.
- - Multiple listen-address directives are supported since 3.0.18, correct the
- documentation to say so.
- - Remove bogus section about long and short being preferable to int.
- - Corrected some Internet JunkBuster references to Privoxy.
- - Removed references to www.junkbusters.com since it is no longer
- maintained. 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 outside 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 potentially 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().
-
-- 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.
-
-- 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.
-
-- 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.
+ - The 'Would you like to donate?' section now also contains
+ a "Paypal" address.
+ - The list of supported operating systems has been updated.
+ - The existence of the SF support and feature trackers has been
+ deemphasized because they have been broken for months.
+ Most of the time the mailing lists still work.
+ - The claim that default.action updates are sometimes released
+ on their own has been removed. It hasn't happened in years.
+ - Explicitly mention that Tor's port may deviate from the default
+ when using a bundle. Requested by Andrew on ijbswa-users@.
