- 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.

- 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:

- - 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.

- that expected an acceptable Referer to be removed.
- - Explain why the "Set Header = Host: whatever.example.org" test is
- expected to fail when using a CGI prefix that starts with "https://".
- - Explain why a connection-sharing test is known to fail
- when using "https://p.p/" as CGI prefix.
