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 3.0.30 --------------------------------------------------------------------- - 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. + - 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. + - Fix a couple of format specifiers. + - Silence compiler warnings when compiling with NDEBUG. + - 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: - - 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. + - 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. - 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/. + - Disable fast-redirects for .golem.de/ + - Unblock requests to adri*. + - Block requests for trc*.taboola.com/ + - Disable fast-redirects for .linkedin.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. + - Make the second pcrs job of the img-reorder filter greedy again. + The ungreedy version broke the img tags on: + https://bulk.fefe.de/scalability/. - 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. + - Clarify the --statistics output. The shown "Reused connections" + are server connections so name them appropriately. + - Bump version to 0.9.3. - 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. It's obviously licensed under - the GNU GPL like the rest of Privoxy or we wouldn't be allowed to - distribute it. - - Update the +hide-user-agent example with uagen output. - - Slightly improve the wording of the ca-key-file documentation. - - Explicitly mention Windows 10 as supported so search engines and - users looking for it can find it. - - Import a bunch of contributors from the ChangeLog. - - Remove obsolete doc/gpl.html. - - Upgrade a couple of links to https://. - - Don't prefer the SourceForge patch tracker over the - privoxy-devel mailing list.
