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>

<p>Bug fixes:</p>
<ul>
pattern while Privoxy has been compiled without FEATURE_PCRE_HOST_PATTERNS. Closes: SF patch request #147.
Patch by Maxim Antonov.</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>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>
<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>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>
+ <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>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>
+ <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>handle_established_connection(): Slightly improve a comment</p>
+ <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>handle_established_connection(): Fix a comment</p>
+ <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>socks5_connect(): Fix indentation.</p>
+ <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>handle_established_connection(): Improve an error message</p>
+ <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>create_pattern_spec(): Fix ifdef indentation</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>Fix comment typos</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

<p>mbedTLS get_ciphersuites_from_string(): Use strlcpy() instead of strncpy(). Previously the terminating
doesn't know that. Get rid of several "this statement may fall through [-Wimplicit-fallthrough=]"
warnings.</p>

<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>
- <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
