-
- <p><span class="APPLICATION">Privoxy 3.0.24</span> stable contains a

+ <h1 class="SECT1"><a name="WHATSNEW" id="WHATSNEW">3. What's New in this Release</a></h1>
+ <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 fixes (denial of service):</p>
-
+ <p>Security/Reliability:</p>
<ul>
<li>
- <p>Prevent invalid reads in case of corrupt chunk-encoded
- content. CVE-2016-1982. Bug discovered with afl-fuzz and
- AddressSanitizer.</p>
+ <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>Remove empty Host headers in client requests. Previously they
- would result in invalid reads. CVE-2016-1983. Bug discovered with
- afl-fuzz and AddressSanitizer.</p>
+ <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>When using socks5t, send the request body optimistically as
- well. Previously the request body wasn't guaranteed to be sent at
- all and the error message incorrectly blamed the server. Fixes
- #1686 reported by Peter Müller and G4JC.</p>
+ <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>Fixed buffer scaling in execute_external_filter() that could
- lead to crashes. Submitted by Yang Xia in #892.</p>
+ <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>Fixed crashes when executing external filters on platforms
- like Mac OS X. Reported by Jonathan McKenzie on
- ijbswa-users@.</p>
+ <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>Properly parse ACL directives with ports when compiled with
- HAVE_RFC2553. Previously the port wasn't removed from the host
- and in case of 'permit-access 127.0.0.1 example.org:80' Privoxy
- would try (and fail) to resolve "example.org:80" instead of
- example.org. Reported by Pak Chan on ijbswa-users@.</p>
+ <p>handle_established_connection(): Slightly improve a comment.</p>
</li>
-
<li>
- <p>Check requests more carefully before serving them forcefully
- when blocks aren't enforced. Privoxy always adds the force token
- at the beginning of the path, but would previously accept it
- anywhere in the request line. This could result in requests being
- served that should be blocked. For example in case of pages that
- were loaded with force and contained JavaScript to create
- additionally requests that embed the origin URL (thus inheriting
- the force prefix). The bug is not considered a security issue and
- the fix does not make it harder for remote sites to intentionally
- circumvent blocks if Privoxy isn't configured to enforce them.
- Fixes #1695 reported by Korda.</p>
+ <p>handle_established_connection(): Fix a comment.</p>
</li>
-
<li>
- <p>Normalize the request line in intercepted requests to make
- rewriting the destination more convenient. Previously rewrites
- for intercepted requests were expected to fail unless $hostport
- was being used, but they failed "the wrong way" and would result
- in an out-of-memory message (vanilla host patterns) or a crash
- (extended host patterns). Reported by "Guybrush Threepwood" in
- #1694.</p>
+ <p>socks5_connect(): Fix indentation.</p>
</li>
-
<li>
- <p>Enable socket lingering for the correct socket. Previously it
- was repeatedly enabled for the listen socket instead of for the
- accepted socket. The bug was found by code inspection and did not
- cause any (reported) issues.</p>
+ <p>handle_established_connection(): Improve an error message.</p>
</li>
-
<li>
- <p>Detect and reject parameters for parameter-less actions.
- Previously they were silently ignored.</p>
+ <p>create_pattern_spec(): Fix ifdef indentation.</p>
</li>
-
<li>
- <p>Fixed invalid reads in internal and outdated pcre code. Found
- with afl-fuzz and AddressSanitizer.</p>
+ <p>Fix comment typos.</p>
</li>
-
<li>
- <p>Prevent invalid read when loading invalid action files. Found
- with afl-fuzz and AddressSanitizer.</p>
+ <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>Windows build: Use the correct function to close the event
- handle. It's unclear if this bug had a negative impact on
- Privoxy's behaviour. Reported by Jarry Xu in #891.</p>
+ <p>chat(): Log the applied actions before deciding how to forward the request.</p>
</li>
-
<li>
- <p>In case of invalid forward-socks5(t) directives, use the
- correct directive name in the error messages. Previously they
- referred to forward-socks4t failures. Reported by Joel Verhagen
- in #889.</p>
+ <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>General improvements:</p>
-
+ <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>
+ <li>
+ <p>Disable fast-redirects for .zeit.de/zustimmung.</p>
+ </li>
+ <li>
+ <p>Unblock adv-archiv.dfn-cert.de/.</p>
+ </li>
+ <li>
+ <p>Block requests to eu-tlp01.kameleoon.eu/.</p>
+ </li>
+ <li>
+ <p>Block requests to fpa-events.arstechnica.com/.</p>
+ </li>
+ <li>
+ <p>Unblock nlnet.nl/.</p>
+ </li>
+ <li>
+ <p>Unblock adguard.com/.</p>
+ </li>
+ </ul>
+ </li>
+ <li>
+ <p>Privoxy-Log-Parser:</p>
<ul>
<li>
- <p>Set NO_DELAY flag for the accepting socket. This significantly
- reduces the latency if the operating system is not configured to
- set the flag by default. Reported by Johan Sintorn in #894.</p>
+ <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>Allow to build with mingw x86_64. Submitted by Rustam
- Abdullaev in #135.</p>
+ <p>Detect date changes when looking for inactivity.</p>
</li>
-
<li>
- <p>Introduce the new forwarding type 'forward-webserver'.
- Currently it is only supported by the forward-override{} action
- and there's no config directive with the same name. The
- forwarding type is similar to 'forward', but the request line
- only contains the path instead of the complete URL.</p>
+ <p>Add a --passed-request-statistics-threshold option that can be set to get statistics for requests that
+ were passed.</p>
</li>
-
<li>
- <p>The CGI editor no longer treats 'standard.action' special.
- Nowadays the official "standards" are part of default.action and
- there's no obvious reason to disallow editing them through the
- cgi editor anyway (if the user decided that the lack of
- authentication isn't an issue in her environment).</p>
+ <p>Add a "inactivity detection" mode which can be useful for debugging purposes.</p>
</li>
-
<li>
- <p>Improved error messages when rejecting intercepted requests
- with unknown destination.</p>
+ <p>Bump version to 0.9.4.</p>
</li>
-
<li>
- <p>A couple of log messages now include the number of active
- threads.</p>
+ <p>Only run print_intro() and print_outro() when syntax highlighting.</p>
</li>
-
<li>
- <p>Removed non-standard Proxy-Agent headers in HTTP snipplets to
- make testing more convenient.</p>
+ <p>Rephrase a sentence in the documentation.</p>
</li>
-
<li>
- <p>Include the error code for pcre errors Privoxy does not
- recognize.</p>
+ <p>Highlight 'Client socket 7 is no longer usable. The server socket has been closed.'.</p>
</li>
-
<li>
- <p>Config directives with numerical arguments are checked more
- carefully.</p>
+ <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>Privoxy's malloc() wrapper has been changed to prevent
- zero-size allocations which should only occur as the result of
- bugs.</p>
+ <p>Fix typo in the --statistics output.</p>
</li>
-
<li>
- <p>Various cosmetic changes.</p>
+ <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>Bump generated Firefox version to 91 (ESR).</p>
+ </li>
+ <li>
+ <p>Bump version to 1.2.3.</p>
+ </li>
+ <li>
+ <p>Bump copyright.</p>

</li>
-
<li>
- <p>Block "abs.proxistore.com/abe/". Reported by Black Rider.</p>
+ <p>Bump copyright.</p>
</li>
-
<li>
- <p>Disable filter{banners-by-size} for
- ".black-mosquito.org/".</p>
+ <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>
- <p>Disable fast-redirects for "disqus.com/".</p>
+ <p>configure: Remove obsolete RPM_BASE check.</p>

<ul>
<li>
- <p>FAQ: Explicitly point fingers at ASUS as an example of a
- company that has been reported to force malware based on Privoxy
- upon its customers.</p>
+ <p>Update the build script to use mbed tls version 2.6.11.</p>
</li>
-
<li>
- <p>Correctly document the action type for a bunch of
- "multi-value" actions that were incorrectly documented to be
- "parameterized". Reported by Gregory Seidman on
- ijbswa-users@.</p>
+ <p>Update build script to use the final 8.45 pcre library.</p>
</li>
-
<li>
- <p>Fixed the documented type of the forward-override{} action
- which is obviously 'parameterized'.</p>
+ <p>Put all the '--enable-xxx' options in the configure call together.</p>
</li>
</ul>
</li>
-
<li>
- <p>Website improvements:</p>
-
+ <p>macOS build system:</p>
<ul>
<li>
- <p>Users who don't trust binaries served by SourceForge can get
- them from a mirror. Migrating away from SourceForge is planned
- for 2016 (TODO list item #53).</p>
+ <p>The OSXPackageBuilder repository has been updated and can be used to create macOS packages again.</p>
+ </li>
+ </ul>
+ </li>
+ <li>
+ <p>Documentation:</p>
+ <ul>
+ <li>
+ <p>contacting: Remove obsolete reference to announce.sgml.</p>
+ </li>
+ <li>
+ <p>contacting: Request that the browser cache is cleared before producing a log file for submission.</p>
+ </li>
+ <li>
+ <p>Sponsor FAQ: Note that Privoxy users may follow sponsor links without Referer header set.</p>
+ </li>
+ <li>
+ <p>newfeatures: Clarify that https inspection also allows to filter https responses.</p>
+ </li>
+ <li>
+ <p>developer-manual: Mention that announce.txt should be updated when doing a release.</p>
+ </li>
+ <li>
+ <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
+ all the debug options that should be enabled when reporting problems or requesting support. Make it easier
+ for users to do the right thing by having all those options present in the config.</p>
+ </li>
+ <li>
+ <p>Update TODO list item #184 to note that WolfSSL support will (hopefully) appear after the 3.0.34
+ release.</p>
+ </li>
+ <li>
+ <p>Update max-client-connections's description. On modern systems other than Windows Privoxy should use
+ 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>The website is now available as onion service

+ 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>
