It mainly contains -bugfixes for the previous betas which introduced IPv6 support, -improved keep-alive support and a bunch of minor improvements. +Privoxy 3.0.31 fixes two security issues that were discovered while +preparing the 3.0.30 release. The issues also affect earlier Privoxy +releases. -See http://www.privoxy.org/3.0.15/user-manual/whatsnew.html for details. +-------------------------------------------------------------------- +ChangeLog for Privoxy 3.0.31 +-------------------------------------------------------------------- +- Security/Reliability: + - Prevent an assertion from getting triggered by a crafted CGI request. + Commit 5bba5b89193fa. OVE-20210130-0001. + Reported by: Joshua Rogers (Opera) + - Fixed a memory leak when decompression fails "unexpectedly". + Commit f431d61740cc0. OVE-20210128-0001. + +- Bug fixes: + - Fixed detection of insufficient data for decompression. + Previously Privoxy could try to decompress a partly + uninitialized buffer. -------------------------------------------------------------------- -ChangeLog for Privoxy +ChangeLog for Privoxy 3.0.30 -------------------------------------------------------------------- -*** Version 3.0.16 stable *** - -- Added the config file option handle-as-empty-doc-returns-ok to - work around Firefox bug #492459, which causes Firefox to hang - if JavaScripts are blocked in certain situations. The option is - enabled in the default config file. -- Added the config file option default-server-timeout to control the - assumed default server timeout. Since Privoxy no longer returns - an error message for connection resets on reused client connections, - assuming larger server timeout values appears to actually work - pretty well as long as connections aren't shared. -- Added optional support for FreeBSD's accf_http(9). Use the - configure option --enable-accept-filter to enable it. -- Added fancier Privoxy icons for win32. Contributed by Jeff H. -- In daemon mode, fd 0, 1 and 2 are bound to /dev/null. -- Resolve localhost using whatever address family the operating - system feels like. Previous betas would try to use IPv4 as this - is what most users expect, but this didn't work reliably on - GNU/Linux systems. -- In the action lists on CGI pages, actions and their parameters are - no longer separated with a space. The action file parser doesn't - actually allow this and will throw an invalid syntax error if actions - and parameters in the action files are separated. Not adding the - spaces means copy and pasting CGI output into the action files works. -- The default keep-alive timeout has been reduced to 5 seconds to work - around hangs in clients that treat the proxy like any other host and - stop allowing any new connections if the "maximum number of - connections per host" is reached. -- Several webbug URLs that look like they are leading to images are now - blocked as image instead of empty documents. Doing the latter causes - WebKit-based clients to show a "missing image" icon which may mess up - the layout. -- The no-such-domain template is used for DNS resolution - problems with FEATURE_IPV6_SUPPORT enabled. Previously the - connect-failed template was used. Reported by 'zebul666'. -- Accepts quoted expiration dates even though RFC 2109 10.1.2 - doesn't seem to allow them. Reported anonymously. -- Don't try to forget connections if connection sharing is disabled. - This wasn't a real problem but caused an unnecessary log message. -- The still undocumented --enable-extended-host-patterns configure - option has a better description. -- Fixed an error message that would claim a write to the server - failed when actually writing to the client failed. -- Log the crunch reason before trying to write to the client. - The log is easier to read that way. -- Several log messages about client connections also mention - the socket number. -- handle-as-empty-document no longer depends on the image blocking - code being enabled. -- Privoxy-Log-Parser is roughly 40% faster in highlighting mode. -- uagen, a Firefox User-Agent generator for Privoxy and Mozilla - browsers has been imported and is available in the tarball's - tools directory. -- The scripts in the tools directory treat unknown parameters - as fatal errors. - -*** Version 3.0.15 beta *** - -- In case of missing server data, no error message is send to the - client if the request arrived on a reused connection. The client - is then supposed to silently retry the request without bothering - the user. This should significantly reduce the frequency of the - "No server or forwarder data received" error message many users - reported. -- More reliable detection of prematurely closed client sockets - with keep-alive enabled. -- FEATURE_CONNECTION_KEEP_ALIVE is decoupled from - FEATURE_CONNECTION_SHARING and now available on - all platforms. -- Improved handling of POST requests on reused connections. - Should fix problems with stalled connections after submitting - form data with some browser configurations. -- Fixed various latency calculation issues. -- Allows the client to pass NTLM authentication requests to a - forwarding proxy. This was already assumed and hinted to work - in 3.0.13 beta but actually didn't. Now it's confirmed to work - with IE, Firefox and Chrome. - Thanks to Francois Botha and Wan-Teh Chang -- Fixed a calculation problem if receiving the server headers - takes more than two reads, that could cause Privoxy to terminate - the connection prematurely. Reported by Oliver. -- Compiles again on platforms such as OpenBSD and systems - using earlier glibc version that don't support AI_ADDRCONFIG. - Anonymously submitted in #2872591. -- A bunch of MS VC project files and Suse and Redhat RPM spec - files have been removed as they were no longer maintained for - quite some time. -- Overly long action lines are properly rejected with a proper - error message. Previously they would be either rejected as - invalid or cause a core dump through abort(). -- Already timed-out connections are no longer temporarily remembered. - They weren't reused anyway, but wasted a socket slot. -- len refers to the number of bytes actually read which might - differ from the ones received. Adjust log messages accordingly. -- The optional JavaScript on the CGI page uses encodeURIComponent() - instead of escape() which doesn't encode all characters that matter. - Anonymously reported in #2832722. -- Fix gcc45 warnings in decompress_iob(). -- Various log message improvements. -- Privoxy-Regression-Test supports redirect tests. -- Privoxy-Log-Parser can gather some connection statistics. - -*** Version 3.0.14 beta *** - -- The latency is taken into account when evaluating whether or not to - reuse a connection. This should significantly reduce the number of - connections problems several users reported. -- If the server doesn't specify how long the connection stays alive, - Privoxy errs on the safe side of caution and assumes it's only a second. -- The error pages for connection timeouts or missing server data use a - Last-Modified date in the past. Retry attempts are detected and Privoxy - removes the If-Modified-Since header to prevent the server from responding - with status code 304 in which case the client would reuse the error message. -- Setting keep-alive-timeout to 0 disables keep-alive support. Previously - Privoxy would claim to allow persistence but not reuse the connection. -- Pipelined requests are less likely to be mistaken for the request - body of the previous request. Note that Privoxy still has no real - pipeline support and will either serialize pipelined requests or - drop them in which case the client has to resent them. -- Fixed a crash on some Windows versions when header randomization - is enabled and the date couldn't be parsed. -- Privoxy's keep-alive timeout for the current connection is reduced - to the one specified in the client's Keep-Alive header. -- For HTTP/1.1 requests, Privoxy implies keep-alive support by not - setting any Connection header instead of using 'Connection: keep-alive'. -- If the socket isn't reusable, Privoxy doesn't temporarily waste - a socket slot to remember the connection. -- If keep-alive support is disabled but compiled in, the client's - Keep-Alive header is removed. -- Fixed a bug on mingw32 where downloading large files failed if - keep-alive support was enabled. -- Fixed a bug that (at least theoretically) could cause log - timestamps to be occasionally off by about a second. -- No Proxy-Connection header if added if there already is one. -- The configure script respects the $PATH variable when searching - for groups and id. - -*** Version 3.0.13 beta *** - -- Added IPv6 support. Thanks to Petr Pisar who not only provided - the initial patch but also helped a lot with the integration. -- Added client-side keep-alive support. -- The connection sharing code is only used if the connection-sharing - option is enabled. -- The max-client-connections option has been added to restrict - the number of client connections below a value enforced by - the operating system. -- Fixed a regression reintroduced in 3.0.12 that could cause - crashes on mingw32 if header date randomization was enabled. -- Compressed content with extra fields couldn't be decompressed - and would get passed to the client unfiltered. This problem - has only be detected through statical analysis with clang as - nobody seems to be using extra fields anyway. -- If the server resets the Connection after sending only the headers - Privoxy forwards what it got to the client. Previously Privoxy - would deliver an error message instead. -- Error messages in case of connection timeouts use the right - HTTP status code. -- If spawning a child to handle a request fails, the client - gets an error message and Privoxy continues to listen for - new requests right away. -- The error messages in case of server-connection timeouts or - prematurely closed server connections are now template-based. -- If zlib support isn't compiled in, Privoxy no longer tries to - filter compressed content unless explicitly asked to do so. -- In case of connections that are denied based on ACL directives, - the memory used for the client IP is no longer leaked. -- Fixed another small memory leak if the client request times out - while waiting for client headers other than the request line. -- The client socket is kept open until the server socket has - been marked as unused. This should increase the chances that - the still-open connection will be reused for the client's next - request to the same destination. Note that this only matters - if connection-sharing is enabled. -- A TODO list has been added to the source tarball to give potential - volunteers a better idea of what the current goals are. + +- Bug fixes: + - Check the actual URL for redirects when https inspecting requests. + Previously Privoxy would only check the path which resulted in + rewrite results being rejected as invalid URLs. + Reported by withoutname in #1736. + - Let the hide-referrer code tolerate Referer headers with https:// URLs. + Previously they would always be treated like a changed host. + - Use the https headers if the show-request handler is reached through + https://. Previously Privoxy would use the http headers which + may be empty on a reused connection. + - Make CGI_PREFIX protocol-relative when building with FEATURE_HTTPS_INSPECTION. + 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. + 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-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. + Fixes SF bug #923 reported by withoutname. + - Add support for filtering client request bodies by using + CLIENT-BODY-FILTER filters which can be enabled with the + client-body-filter action. + Patch submitted by Maxim Antonov. + Sponsored by: Robert Klemme + - Add the new action suppress-tag{} which can be used to prevent + a tagger from adding a tag. Patch submitted by Maxim Antonov. + Sponsored by: Robert Klemme + - Gracefully handle existing website keys without matching certificates. + This can happen if Privoxy was previously running with an invalid + TLS configuration that didn't allow it to create a certificate. + - Recycle debug bit 4 for Tagging-related messages. + - Improve the message shown when the client-tags CGI page + is requested with no tags configured. + - Shorten the 'donate' and 'participate' links used by templates + using redirects. Currently the redirects lead to the FAQ entries + but in the future we may want to relocate the content and using + redirects makes this more convenient. + - Log an error when a PCRE-HOST-PATTERN is used with + FEATURE_PCRE_HOST_PATTERNS disabled. Don't treat this a + fatal error so the regression tests can be used with and + without FEATURE_PCRE_HOST_PATTERNS. + - The code compiles with older C compilers again. + - 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. + - Fixed harmless compiler warnings from GCC9 with -D_FORTIFY_SOURCE=2. + - windows: Remove obsolete '$(DEST)/doc/images' target. + - windows: Install the images referenced in the user manual. + - Remove obsolete 'gnu_regex.@OBJEXT@' target. + - When installing from the GNUMAkefile, don't create an 'images' + 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. + - Remove unused variable in the OpenSSL-specific code. + - Update bug tracker URL in cgi_error_unknown(). + - Saved a couple of memory allocations when sorting client headers. + - Improved a couple of error messages. + - Saved memory allocations when using OpenSSL and checking if a + key already exists. + - 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. + +- Action file improvements: + - Block requests to eu-tlp03.kameleoon.com/. + - Unblock metrics.sr.ht/. + - Disable fast-redirects for .fsf.org/. + - Disable fast-redirects for .gravater.com/. + - Disable fast-redirects for .ksta.de/. + - Block requests to tag.crsspxl.com/. + - Block requests to analytics.slashdotmedia.com/. + - Block requests to ml314.com/. + - Block requests to .adroll.com/. + - Block requests to fastlane.rubiconproject.com/. + - Block requests to api.theadex.com/. + - Block requests to ih.adscale.de/. + - Block requests to .s400.meetrics.net/. + - Block requests for pp.lp4.io/. + - Block requests for trc-events.taboola.com/. + +- Filter file improvements: + - A allow-autocompletion filter has been added which changes + autocomplete="off" to "on" on input fields to allow autocompletion. + Requested by Jamie Zawinski in #370. + Filter based on a submission by Aaron Linville. + - Added an imdb filter. + - Added a sourceforge filter that reduces the amount of ads + for proprietary software. + - Added a github filter that removes the annoying "Sign-Up" + banner and the Cookie disclaimer. + - Removed a duplicated pcrs command from the js-annoyances filter. + - The crude-parental filter now provides a short reason when blocking, + inserts a link to Privoxy's webinterface and adds a new line at + the end of the generated page. + +- Privoxy-Log-Parser: + - Highlight a few more messages. + - Add a handler for tagging messages. + - Properly deal with 'Certificate error' crunches + Previously the error description was highlighted as 'host'. + - Log truncated LOG_LEVEL_CLF messages more gracefully + and note that the statistics will be imprecise. + - Fixed perldoc typo. + - Bump version to 0.9.2. + +- Privoxy-Regression-Test: + - Use http://127.0.0.1:8118/ as default Privoxy address + unless http_proxy is set through the environment. + - Add a --privoxy-cgi-prefix option that specifies the prefix + to use when building URLs that are supposed to reach Privoxy's + CGI interface. If it's not set, http://p.p/ is used, which is + supposed to work with the default Privoxy configuration. + If Privoxy has been built with FEATURE_HTTPS_INSPECTION enabled, + and if https inspection is activated with the +https-inspection + action, this option can be used with "https://p.p/" provided the + system running Privoxy-Regression-Test has been configured to + trust the certificate used by Privoxy. + Note that there are currently two tests in the official + regression-tests.action file that are expected to fail + when using "https://p.p/" as privoxy-cgi-prefix. + - Skip the connection-established response in get_status_code() + when looking for the status code with a CGI prefix + that starts with https://. We care about the status code + sent by the impersonated web server. + - Use --proxy-header when using a CGI prefix with https:// + and a "Host:" header. + - Allow '|' in tokens and values to allow tag patterns like + "TAG:^(application|text)/(x-)?javascript$". + - When get_cgi_page_or_else() fails, include the URL of the + requested page in the log message. + - Added a --check-bad-ssl option that can be used to verify that + Privoxy detects certificate problems when accessing the test + sites from badssl.com. + - Bumped version to 0.7.2 + +- uagen: + - Update example output. + - Recommend the use of the https-inspection action in the documentation. + - Upgrade a couple of URLs to https://. + - Add ElectroBSD to the list of operating systems. + - Bumped generated Firefox version to 78 (ESR). + - Bumped version to 1.2.2. + + - User documentation: + - Remove reference to 'How to Report Bugs Effectively'. + It was only rendered as text without URL in the README anyway + and there's no indication that users read it ... + - Let the dok-readme target fix the location embedded into the + README file. This used to be done by CVS but since the git migration + it has to be done through other means. + - Remove 'experimental' warning for client-specific-tag-related directives. + They seem to work reliably and there is no obvious reason + why we would change the syntax in the near future. + - Describe how to check if Privoxy has been built with + FEATURE_HTTPS_INSPECTION. + - Add a link to the trusted-cas-file documentation + that explains how the user can create the file herself. + - Don't explicitly mention the license for the code coming from + 'Anonymous Coders' and Junkbusters.
