+ <p><span class="APPLICATION">Privoxy 3.0.33</span> fixes an XSS issue and multiple DoS issues and a couple of other
+ bugs. The issues also affect earlier Privoxy releases. <span class="APPLICATION">Privoxy 3.0.33</span> also comes
+ with a couple of general improvements an new features.</p>
+ <p>Changes in <span class="APPLICATION">Privoxy 3.0.33</span> stable:</p>
+ <ul>
+ <li>
+ <p>Security/Reliability:</p>
+ <ul>
+ <li>
+ <p>cgi_error_no_template(): Encode the template name to prevent XSS (cross-side scripting) when Privoxy is
+ configured to servce the user-manual itself. Commit 0e668e9409c. OVE-20211102-0001. CVE-2021-44543.
+ Reported by: Artem Ivanov</p>
+ </li>
+ <li>
+ <p>get_url_spec_param(): Free memory of compiled pattern spec before bailing. Reported by Joshua Rogers
+ (Opera) who also provided the fix. Commit 652b4b7cb0. OVE-20211201-0003. CVE-2021-44540.</p>
+ </li>
+ <li>
+ <p>process_encrypted_request_headers(): Free header memory when failing to get the request destination.
+ Reported by Joshua Rogers (Opera) who also provided the fix. Commit 0509c58045. OVE-20211201-0002.
+ CVE-2021-44541.</p>
+ </li>
+ <li>
+ <p>send_http_request(): Prevent memory leaks when handling errors Reported by Joshua Rogers (Opera) who
+ also provided the fix. Commit c48d1d6d08. OVE-20211201-0001. CVE-2021-44542.</p>
+ </li>
+ </ul>
+ </li>
+ <li>
+ <p>Bug fixes:</p>
+ <ul>
+ <li>
+ <p>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.</p>
+ </li>
+ <li>
+ <p>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.</p>
+ </li>
+ <li>
+ <p>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.</p>
+ </li>
+ <li>
+ <p>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.</p>
+ </li>
+ <li>
+ <p>load_config(): Add a space that was missing in a log message.</p>
+ </li>
+ <li>
+ <p>read_http_request_body(): Fix two error messages that used an incorrect variable.</p>
+ </li>
+ <li>
+ <p>If the the response is chunk-encoded, ignore the Content-Length header sent by the server. Allows to
+ load https://redmine.lighttpd.net/ with filtering enabled.</p>
+ </li>
+ </ul>
+ </li>
+ <li>
+ <p>General improvements:</p>
+ <ul>
+ <li>
+ <p>Allow to edit the add-header action through the CGI editor by generalizing the code that got added with
+ the suppress-tag action. Closes SF patch request #146. Patch by Maxim Antonov.</p>
+ </li>
+ <li>
+ <p>Add a CGI handler for /wpad.dat that returns a Proxy Auto-Configuration (PAC) file. Among other things,
+ it can be used to instruct clients through DHCP to use Privoxy as proxy. For example with the dnsmasq
+ option: dhcp-option=252,http://config.privoxy.org/wpad.dat Initial patch by Richard Schneidt.</p>
+ </li>
+ <li>
+ <p>Don't log the applied actions in process_encrypted_request() Log them in continue_https_chat() instead
+ to mirror chat(). Prevents the applied actions from getting logged twice for the first request on an
+ https-inspected connection.</p>
+ </li>
+ <li>
+ <p>OpenSSL generate_host_certificate(): Use config.privoxy.org as Common Name Org and Org Unit if the real
+ host name is too long to get accepted by OpenSSL. Clients should only care about the Subject Alternative
+ Name anyway and we can continue to use the real host name for it. Reported by Miles Wen on
+ privoxy-users@.</p>
+ </li>
+ <li>
+ <p>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.</p>
+ </li>
+ <li>
+ <p>listen_loop(): When shutting down gracefully, close listening ports before waiting for the threads to
+ exit. Allows to start a second Privoxy with the same config file while the first Privoxy is still
+ running.</p>
+ </li>
+ <li>
+ <p>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.</p>
+ </li>
+ <li>
+ <p>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.</p>
+ </li>
+ <li>
+ <p>handle_established_connection(): Slightly improve a comment.</p>
+ </li>
+ <li>
+ <p>handle_established_connection(): Fix a comment.</p>
+ </li>
+ <li>
+ <p>socks5_connect(): Fix indentation.</p>
+ </li>
+ <li>
+ <p>handle_established_connection(): Improve an error message.</p>
+ </li>
+ <li>
+ <p>create_pattern_spec(): Fix ifdef indentation.</p>
+ </li>
+ <li>
+ <p>Fix comment typos.</p>
+ </li>
+ <li>
+ <p>process_encrypted_request(): Improve a log message. The function only processes request headers and
+ there may still be unread request body data left to process.</p>
+ </li>
+ <li>
+ <p>chat(): Log the applied actions before deciding how to forward the request.</p>
+ </li>
+ <li>
+ <p>parse_time_header(): Silence a coverity complaint when building without assertions.</p>
+ </li>
+ <li>
+ <p>receive_encrypted_request_headers(): Improve a log message.</p>
+ </li>
+ <li>
+ <p>mbedTLS get_ciphersuites_from_string(): Use strlcpy() instead of strncpy(). Previously the terminating
+ NUL wasn't copied which resulted in a compiler warning. This didn't cause actual problems as the target
+ buffer was initialized by zalloc_or_die() so the last byte of the target buffer was NUL already. Actually
+ copying the terminating NUL seems clearer, though.</p>
+ </li>
+ <li>
+ <p>Remove compiler warnings. "log_error(LOG_LEVEL_FATAL, ..." doesn't return but apparently the compiler
+ doesn't know that. Get rid of several "this statement may fall through [-Wimplicit-fallthrough=]"
+ warnings.</p>
+ </li>
+ <li>
+ <p>Store the PEM certificate in a dynamically allocated buffer when https-inspecting. Should prevent errors
+ like: 2021-03-16 22:36:19.148 7f47bbfff700 Error: X509 PEM cert len 16694 is larger than buffer len 16383
+ As a bonus it should slightly reduce the memory usage as most certificates are smaller than the previously
+ used fixed buffer. Reported by: Wen Yue</p>
+ </li>
+ <li>
+ <p>OpenSSL generate_host_certificate(): Fix two error messsages.</p>
+ </li>
+ <li>
+ <p>Improve description of handle_established_connection()</p>
+ </li>
+ <li>
+ <p>OpenSSL ssl_store_cert(): Translate EVP_PKEY_EC to a string.</p>
+ </li>
+ <li>
+ <p>OpenSSL ssl_store_cert(): Remove pointless variable initialization.</p>
+ </li>
+ <li>
+ <p>OpenSSL ssl_store_cert(): Initialize pointer with NULL instead of 0.</p>
+ </li>
+ </ul>
+ </li>
+ <li>
+ <p>Action file improvements:</p>
+ <ul>
+ <li>
+ <p>Disable fast-redirects for .microsoftonline.com/.</p>
+ </li>
+ <li>
+ <p>Disable fast-redirects for idp.springer.com/.</p>

+ <li>
+ <p>Disable fast-redirects for .zeit.de/zustimmung.</p>

+ </li>
+ </ul>
+ </li>
+ <li>
+ <p>Privoxy-Log-Parser:</p>
+ <ul>
+ <li>
+ <p>Highlight 'Socket timeout 3 reached: http://127.0.0.1:20000/no-filter/chunked-content/36'.</p>
+ </li>
+ <li>
+ <p>Improve documentation for inactivity-detection mode.</p>
+ </li>
+ <li>
+ <p>Detect date changes when looking for inactivity.</p>
+ </li>
+ <li>
+ <p>Add a --passed-request-statistics-threshold option that can be set to get statistics for requests that
+ were passed.</p>
+ </li>
+ <li>
+ <p>Add a "inactivity detection" mode which can be useful for debugging purposes.</p>
+ </li>
+ <li>
+ <p>Bump version to 0.9.4.</p>
+ </li>
+ <li>
+ <p>Only run print_intro() and print_outro() when syntax highlighting.</p>
+ </li>
+ <li>
+ <p>Rephrase a sentence in the documentation.</p>
+ </li>
+ <li>
+ <p>Highlight 'Client socket 7 is no longer usable. The server socket has been closed.'.</p>
+ </li>
+ <li>
+ <p>Clarify --statistics output by explicitly mentioning that the status codes sent by the server may differ
+ from the ones in "debug 512" messages.</p>
+ </li>
+ <li>
+ <p>Fix typo in the --statistics output.</p>
+ </li>
+ <li>
+ <p>Remove an unused variable.</p>
+ </li>
+ <li>
+ <p>Highlight 'The peer notified us that the connection on socket 11 is going to be closed'.</p>
+ </li>
+ </ul>
+ </li>
+ <li>
+ <p>Privoxy-Regression-Test:</p>
+ <ul>

+ <p>Remove duplicated word in a comment.</p>
+ </li>
+ </ul>
+ </li>
+ <li>
+ <p>regression-tests.action:</p>
+ <ul>
+ <li>
+ <p>Add fetch test for http://p.p/wpad.dat.</p>
+ </li>
+ <li>
+ <p>Bump for-privoxy-version to 3.0.33 which introduced the wpad.dat support.</p>
+ </li>
+ <li>
+ <p>Add more tests for the '/send-banner' code.</p>
+ </li>
+ <li>
+ <p>Add test for OVE-20210203-0001.</p>
+ </li>
+ <li>
+ <p>Add a test for CVE-2021-20217.</p>

+ <li>
+ <p>Bump copyright.</p>
+ </li>
+ <li>
+ <p>Add a configure option to disable pcre JIT compilation. While JIT compilation makes filtering faster it
+ can cause false-positive valgrind complaints. As reported by Gwyn Ciesla in SF bug 924 it also can cause
+ problems when the SELinux policy does not grant Privoxy "execmem" privileges.</p>
+ </li>

+ </li>
+ <li>
+ <p>developer-manual: Mention that announce.txt should be updated when doing a release.</p>

+ <p>config: Explicitly mention that the CGI pages disclosing the ca-password can be blocked and upgrade the
+ disclosure paragraphs to a warning.</p>
+ </li>
+ <li>
+ <p>Put all the requested debug options in the config file. Section 11.1 of the Privoxy user manual lists

+ poll() in which case the FD_SETSIZE value isn't releveant.</p>
+ </li>
+ <li>
+ <p>Add a warning that the socket-timeout does not apply to operations done by TLS libraries.</p>
+ </li>
+ <li>
+ <p>Make documentation slightly less "offensive" for some people by avoiding the word "hell".</p>
+ </li>

+ <h2 class="SECT2"><a name="UPGRADERSNOTE" id="UPGRADERSNOTE">3.1. Note to Upgraders</a></h2>
+ <p>A quick list of things to be aware of before upgrading from earlier versions of <span class=
+ "APPLICATION">Privoxy</span>:</p>
<ul>
<li>
- <p>
- Fixed last-chunk-detection for responses where the content was
- small enough to be read with the body, causing Privoxy to wait
- for the end of the content until the server closed the connection
- or the request timed out. Reported by "Karsten" in #3028326.
- </p>
- </li>
- <li>
- <p>
- Responses with status code 204 weren't properly detected as
- body-less like RFC2616 mandates. Like the previous bug, this
- caused Privoxy to wait for the end of the content until the
- server closed the connection or the request timed out. Fixes
- #3022042 and #3025553, reported by a user with no visible name.
- Most likely also fixes a bunch of other AJAX-related problem
- reports that got closed in the past due to insufficient
- information and lack of feedback.
- </p>
- </li>
- <li>
- <p>
- Fixed an ACL bug that made it impossible to build a blacklist.
- Usually the ACL directives are used in a whitelist, which worked
- as expected, but blacklisting is still useful for public proxies
- where one only needs to deny known abusers access.
- </p>
- </li>
- <li>
- <p>
- Added LOG_LEVEL_RECEIVED to log the not-yet-parsed data read from
- the network. This should make debugging various parsing issues a
- lot easier.
- </p>
+ <p>The recommended way to upgrade <span class="APPLICATION">Privoxy</span> is to backup your old
+ configuration files, install the new ones, verify that <span class="APPLICATION">Privoxy</span> is working
+ correctly and finally merge back your changes using <span class="APPLICATION">diff</span> and maybe
+ <span class="APPLICATION">patch</span>.</p>
+ <p>There are a number of new features in each <span class="APPLICATION">Privoxy</span> release and most of
+ them have to be explicitly enabled in the configuration files. Old configuration files obviously don't do
+ that and due to syntax changes using old configuration files with a new <span class=
+ "APPLICATION">Privoxy</span> isn't always possible anyway.</p>
</li>
<li>
- <p>
- The IPv6 code is enabled by default on Windows versions that
- support it. Patch submitted by oCameLo in #2942729.
- </p>
+ <p>Note that some installers remove earlier versions completely, including configuration files, therefore you
+ should really save any important configuration files!</p>
</li>
<li>
- <p>
- In mingw32 versions, the user.filter file is reachable through
- the GUI, just like default.filter is. Feature request 3040263.
- </p>
+ <p>On the other hand, other installers don't overwrite existing configuration files, thinking you will want
+ to do that yourself.</p>
</li>
<li>
- <p>
- Added the configure option --enable-large-file-support to set a
- few defines that are required by platforms like GNU/Linux to
- support files larger then 2GB. Mainly interesting for users
- without proper logfile management.
- </p>
+ <p>In the default configuration only fatal errors are logged now. You can change that in the <a href=
+ "config.html#DEBUG">debug section</a> of the configuration file. You may also want to enable more verbose
+ logging until you verified that the new <span class="APPLICATION">Privoxy</span> version is working as
+ expected.</p>
</li>
<li>
- <p>
- Logging with "debug 16" no longer stops at the first nul byte
- which is pretty useless. Non-printable characters are replaced
- with their hex value so the result can't span multiple lines
- making parsing them harder then necessary.
- </p>
- </li>
- <li>
- <p>
- Privoxy logs when reading an action, filter or trust file.
- </p>
- </li>
- <li>
- <p>
- Fixed incorrect regression test markup which caused a test in
- 3.0.16 to fail while Privoxy itself was working correctly. While
- Privoxy accepts hide-referer, too, the action name is actually
- hide-referrer which is also the name used one the final results
- page, where the test expected the alias.
- </p>
- </li>
- <li>
- <p>
- CGI interface improvements:
- </p>
- <ul>
- <li>
- <p>
- In finish_http_response(), continue to add the 'Connection:
- close' header if the client connection will not be kept
- alive. Anonymously pointed out in #2987454.
- </p>
- </li>
- <li>
- <p>
- Apostrophes in block messages no longer cause parse errors
- when the blocked page is viewed with JavaScript enabled.
- Reported by dg1727 in #3062296.
- </p>
- </li>
- <li>
- <p>
- Fix a bunch of anchors that used underscores instead of
- dashes.
- </p>
- </li>
- <li>
- <p>
- Allow to keep the client connection alive after crunching the
- previous request. Already opened server connections can be
- kept alive, too.
- </p>
- </li>
- <li>
- <p>
- In cgi_show_url_info(), don't forget to prefix URLs that only
- contain http:// or https:// in the path. Fixes #2975765
- reported by Adam Piggott.
- </p>
- </li>
- <li>
- <p>
- Show the 404 CGI page if cgi_send_user_manual() is called
- while local user manual delivery is disabled.
- </p>
- </li>
- </ul>
- </li>
- <li>
- <p>
- Action file improvements:
- </p>
- <ul>
- <li>
- <p>
- Enable user.filter by default. Suggested by David White in
- #3001830.

- <p>

- </ul>
- </li>
- <li>
- <p>
- GNUmakefile improvements:
- </p>

- <a name="UPGRADERSNOTE">3.1. Note to Upgraders</a>
- </h2>
- <p>
- A quick list of things to be aware of before upgrading from earlier
- versions of <span class="APPLICATION">Privoxy</span>:
- </p>
- <p>
- </p>
- <ul>
- <li>
- <p>
- The recommended way to upgrade <span class=
- "APPLICATION">Privoxy</span> is to backup your old
- configuration files, install the new ones, verify that <span
- class="APPLICATION">Privoxy</span> is working correctly and
- finally merge back your changes using <span class=
- "APPLICATION">diff</span> and maybe <span class=
- "APPLICATION">patch</span>.
- </p>
- <p>
- There are a number of new features in each <span class=
- "APPLICATION">Privoxy</span> release and most of them have to
- be explicitly enabled in the configuration files. Old
- configuration files obviously don't do that and due to syntax
- changes using old configuration files with a new <span class=
- "APPLICATION">Privoxy</span> isn't always possible anyway.
- </p>
- </li>
- <li>
- <p>
- Note that some installers remove earlier versions completely,
- including configuration files, therefore you should really save
- any important configuration files!
- </p>
- </li>
- <li>
- <p>
- On the other hand, other installers don't overwrite existing
- configuration files, thinking you will want to do that
- yourself.
- </p>
- </li>
- <li>
- <p>
- <tt class="FILENAME">standard.action</tt> has been merged into
- the <tt class="FILENAME">default.action</tt> file.
- </p>
- </li>
- <li>
- <p>
- In the default configuration only fatal errors are logged now.
- You can change that in the <a href="config.html#DEBUG">debug
- section</a> of the configuration file. You may also want to
- enable more verbose logging until you verified that the new
- <span class="APPLICATION">Privoxy</span> version is working as
- expected.
- </p>
- </li>
- <li>
- <p>
- Three other config file settings are now off by default: <a
- href=
- "config.html#ENABLE-REMOTE-TOGGLE">enable-remote-toggle</a>, <a
- href=
- "config.html#ENABLE-REMOTE-HTTP-TOGGLE">enable-remote-http-toggle</a>,
- and <a href=
- "config.html#ENABLE-EDIT-ACTIONS">enable-edit-actions</a>. If
- you use or want these, you will need to explicitly enable them,
- and be aware of the security issues involved.
