One new feature (tolerate-pipelining) is enabled by default. See below for details. +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 3.0.20 Beta *** +*** Version 3.0.23 stable *** - 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. + - 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: - - 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. - -*** Version 3.0.19 Stable *** - -- Bug fixes: - - Prevent a segmentation fault when de-chunking buffered content. - It could be triggered by malicious web servers if Privoxy was - configured to filter the content and running on a platform - where SIZE_T_MAX isn't larger than UINT_MAX, which probably - includes most 32-bit systems. On those platforms, all Privoxy - versions before 3.0.19 appear to be affected. - To be on the safe side, this bug should be presumed to allow - code execution as proving that it doesn't seems unrealistic. - - Do not expect a response from the SOCKS4/4A server until it - got something to respond to. This regression was introduced - in 3.0.18 and prevented the SOCKS4/4A negotiation from working. - Reported by qqqqqw in #3459781. - -- General improvements: - - Fix an off-by-one in an error message about connect failures. - - Use a GNUMakefile variable for the webserver root directory and - update the path. Sourceforge changed it which broke various - web-related targets. - - Update the CODE_STATUS description. + - 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: + - '.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: + - 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.
