ChangeLog for Privoxy
--------------------------------------------------------------------
+*** Version 3.0.33 UNRELEASED ***
+
+- Bug fixes:
+ - handle_established_connection(): Skip the poll()/select() calls
+ if TLS data is pending on the server socket. The TLS library may
+ have already consumed all the data from the server response in
+ which case poll() and select() will not detect that data is
+ available to be read.
+ Fixes SF bug #926 reported by Wen Yue.
+ - continue_https_chat(): Update csp->server_connection.request_sent
+ after sending the request to make sure the latency is calculated
+ correctly. Previously https connections were not reused after
+ timeout seconds after the first request made on the connection.
+ - free_pattern_spec(): Don't try to free an invalid pointer
+ when unloading an action file with a TAG pattern while
+ Privoxy has been compiled without FEATURE_PCRE_HOST_PATTERNS.
+ Closes: SF patch request #147. Patch by Maxim Antonov.
+ - Establish the TLS connection with the client earlier and decide
+ how to route the request afterwards. This allows to change the
+ forwarding settings based on information from the https-inspected
+ request, for example the path.
+ Adjust build_request_line() to create a CONNECT request line when
+ https-inspecting and forwarding to a HTTP proxy.
+ Fixes SF bug #925 reported by Wen Yue.
+ - load_config(): Add a space that was missing in a log message.
+
+- General improvements:
+ - serve(): Close the client socket as well if the server socket
+ for an inspected connection has been closed. Privoxy currently
+ can't establish a new server connection when the client socket
+ is reused and would drop the connection in continue_https_chat()
+ anyway.
+ - Don't disable redirect checkers in redirect_url()
+ Disable them in handle_established_connection() instead.
+ Doing it in redirect_url() prevented the +redirect{} and
+ +fast-redirects{} actions from being logged with LOG_LEVEL_ACTIONS.
+ - handle_established_connection(): Slightly improve a comment
+ - handle_established_connection(): Fix a comment
+ - socks5_connect(): Fix indentation.
+ - handle_established_connection(): Improve an error message
+ - create_pattern_spec(): Fix ifdef indentation
+ - Fix comment typos
+
+- Action file improvements:
+ - Disable fast-redirects for .microsoftonline.com/.
+ - Disable fast-redirects for idp.springer.com/.
+
+- Privoxy-Regression-Test:
+ - Remove duplicated word in a comment.
+
+- Documentation:
+ - contacting: Remove obsolete reference to announce.sgml.
+ - contacting: Request that the browser cache is cleared before
+ producing a log file for submission.
+ - Sponsor FAQ: Note that Privoxy users may follow sponsor links
+ without Referer header set.
+ - newfeatures: Clarify that https inspection also allows to
+ filter https responses.
+ - developer-manual: Mention that announce.txt should be updated
+ when doing a release.
+
+*** Version 3.0.32 stable ***
+
+- Security/Reliability:
+ - ssplit(): Remove an assertion that could be triggered with a
+ crafted CGI request.
+ Commit 2256d7b4d67. OVE-20210203-0001. CVE-2021-20272.
+ Reported by: Joshua Rogers (Opera)
+ - cgi_send_banner(): Overrule invalid image types. Prevents a
+ crash with a crafted CGI request if Privoxy is toggled off.
+ Commit e711c505c48. OVE-20210206-0001. CVE-2021-20273.
+ Reported by: Joshua Rogers (Opera)
+ - socks5_connect(): Don't try to send credentials when none are
+ configured. Fixes a crash due to a NULL-pointer dereference
+ when the socks server misbehaves.
+ Commit 85817cc55b9. OVE-20210207-0001. CVE-2021-20274.
+ Reported by: Joshua Rogers (Opera)
+ - chunked_body_is_complete(): Prevent an invalid read of size two.
+ Commit a912ba7bc9c. OVE-20210205-0001. CVE-2021-20275.
+ Reported by: Joshua Rogers (Opera)
+ - Obsolete pcre: Prevent invalid memory accesses with an invalid
+ pattern passed to pcre_compile(). Note that the obsolete pcre code
+ is scheduled to be removed before the 3.0.33 release. There has been
+ a warning since 2008 already.
+ Commit 28512e5b624. OVE-20210222-0001. CVE-2021-20276.
+ Reported by: Joshua Rogers (Opera)
+
+- Bug fixes:
+ - 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:
+ - 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:
+ - 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:
+ - 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.
+ - Clarify the --statistics output. The shown "Reused connections"
+ are server connections so name them appropriately.
+ - Bump version to 0.9.3.
+
+- Privoxy-Regression-Test:
+ - Add the --check-bad-ssl option to the --help output.
+ - Bump version to 0.7.3.
+
+- Documentation:
+ - Add pushing the created tag to the release steps in the developer manual.
+ - Clarify that 'debug 32768' should be used in addition to the other debug
+ directives when reporting problems.
+ - Add a 'Third-party licenses and copyrights' section to the user manual.
+
