-> Bug fixes:
- </P
-><P
-></P
-><UL
-><LI
-><P
-> Always use the current toggle state for new requests.
- Previously new requests on reused connections inherited
- the toggle state from the previous request even though
- the toggle state could have changed.
- Reported by Robert Klemme.
- </P
-></LI
-><LI
-><P
-> Fixed two buffer-overflows in the (deprecated) static

-></LI
-></UL
-></LI
-><LI
-><P
-> General improvements:
- </P
-><P
-></P
-><UL
-><LI
-><P
-> Added support for client-specific tags which allow Privoxy
- admins to pre-define tags that are set for all requests from
- clients that previously opted in through the CGI interface.
- They are useful in multi-user setups where admins may
- want to allow users to disable certain actions and filters
- for themselves without affecting others.
- In single-user setups they are useful to allow more fine-grained
- toggling. For example to disable request blocking while still
- crunching cookies, or to disable experimental filters only.
- This is an experimental feature, the syntax and behaviour may
- change in future versions.
- Sponsored by Robert Klemme.
- </P
-></LI
-><LI
-><P
-> Dynamic filters and taggers now support a $listen-address variable
- which contains the address the request came in on.
- For external filters the variable is called $PRIVOXY_LISTEN_ADDRESS.
- Original patch contributed by pursievro.
- </P
-></LI
-><LI
-><P
-> Add client-header-tagger 'listen-address'.
- </P
-></LI
-><LI
-><P
-> Include the listen-address in the log message when logging new requests.
- Patch contributed by pursievro.
- </P
-></LI
-><LI
-><P
-> Turn invalid max-client-connections values into fatal errors.
- </P
-></LI
-><LI
-><P
-> The show-status page now shows whether or not dates before 1970
- and after 2038 are expected to be handled properly.
- This is mainly useful for Privoxy-Regression-Test but could
- also come handy when dealing with time-related support requests.
- </P
-></LI
-><LI
-><P
-> On Mac OS X the thread id in log messages are more likely to
- be unique now.
- </P
-></LI
-><LI

- as well.
- </P

-> A couple of harmless coverity warnings were silenced
- (CID #161202, CID #161203, CID #161211).

-><P
-> Filtering is disabled for Range requests to let download resumption
- and Windows updates work with the default configuration.
- </P

- mention the archives at SF in the contacting section
- for now.
- </P
-></LI
-><LI
-><P
-> Note that the templates should be adjusted if Privoxy is
- running as intercepting proxy without getting all requests.
- </P
-></LI
-><LI
-><P
-> A bunch of links were converted to https://.
- </P
-></LI
-><LI
-><P
-> Rephrase onion service paragraph to make it more obvious
- that Tor is involved and that the whole website (and not
- just the homepage) is available as onion service.
- </P
-></LI
-><LI
-><P
-> Streamline the "More information" section on the homepage further
- by additionally ditching the link to the 'See also' section
- of the user manual. The section contains mostly links that are
- directly reachable from the homepage already and the rest is
- not significant enough to get a link from the homepage.
- </P
-></LI
-><LI
-><P
-> Change the add-header{} example to set the DNT header
- and use a complete section to make copy and pasting
- more convenient.
- Add a comment to make it obvious that adding the
- header is not recommended for obvious reasons.
- Using the DNT header as example was suggested by
- Leo Wzukw.
- </P
-></LI
-><LI
-><P
-> Streamline the support-and-service template
- Instead of linking to the various support trackers
- (whose URLs hopefully change soon), link to the
- contact section of the user manual to increase the
- chances that users actually read it.
- </P
-></LI
-><LI
-><P
-> Add a FAQ entry for tainted sockets.
- </P
-></LI
-><LI
-><P
-> More sections in the documentation have stable URLs now.

-><LI
-><P
-> FAQ: Explain why 'ping config.privoxy.org' is not expected
- to reach a local Privoxy installation.
- </P
-></LI
-><LI
-><P
-> Note that donations done through Zwiebelfreunde e.V. currently
- can't be checked automatically.
- </P
-></LI
-><LI
-><P
-> Updated section regarding starting Privoxy under OS X.
- </P
-></LI
-><LI
-><P
-> Use dedicated start instructions for FreeBSD and ElectroBSD.

- gen-dist target. The package isn't a source distribution but a
- binary package.
- While at it, use a variable for the name to reduce the chances
- that the various references get out of sync and fix the gen-upload
- target which was looking in the wrong directory.
- </P

-> Add a "Default level offset" directive which can be used to
- change the default level by a given value.
- This directive affects all tests located after it until the end
- of the file or a another "Default level offset" directive is reached.
- The purpose of this directive is to make it more convenient to skip
- similar tests in a given file without having to remove or disable
- the tests completely.
- </P

-> Let test level 17 depend on FEATURE_64_BIT_TIME_T

+ <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>

+ <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>

+ <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>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>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.</p>
