+ 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>
+ <p>Bug fixes:</p>
<ul>
<li>
- <p>ssplit(): Remove an assertion that could be triggered with a crafted CGI request. Commit 2256d7b4d67.
- OVE-20210203-0001. Reported by: Joshua Rogers (Opera)</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>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. Reported by: Joshua Rogers (Opera)</p>
+ <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>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. Reported
- by: Joshua Rogers (Opera)</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>chunked_body_is_complete(): Prevent an invalid read of size two. Commit a912ba7bc9c. OVE-20210205-0001.
- Reported by: Joshua Rogers (Opera)</p>
+ <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>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. Reported by: Joshua Rogers (Opera)</p>
+ <p>load_config(): Add a space that was missing in a log message.</p>
</li>
</ul>
</li>
<li>
- <p>Bug fixes:</p>
+ <p>General improvements:</p>
<ul>
<li>
- <p>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)</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>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>decompress_iob(): Prevent reading of uninitialized data. Reported by: Joshua Rogers (Opera).</p>
+ <p>handle_established_connection(): Improve an error message</p>
</li>
<li>
- <p>decompress_iob(): Don't advance cur past eod when looking for the end of the file name and comment.</p>
+ <p>create_pattern_spec(): Fix ifdef indentation</p>
</li>
<li>
- <p>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)</p>
+ <p>Fix comment typos</p>
</li>
<li>
- <p>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).</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>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)</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>log_error(): Treat LOG_LEVEL_FATAL as fatal even when --stfu is being used while fuzzing. Reported by:
- Joshua Rogers (Opera).</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>Respect DESTDIR when considering whether or not to install config files with ".new" extension.</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>OpenSSL ssl_store_cert(): Fix two error messages.</p>
+ <p>read_http_request_body(): Fix two error messages that used an incorrect variable.</p>
</li>
<li>
- <p>Fix a couple of format specifiers.</p>
+ <p>chat(): Log the applied actions before deciding how to forward the request.</p>
</li>
<li>
- <p>Silence compiler warnings when compiling with NDEBUG.</p>
+ <p>parse_time_header(): Silence a coverity complaint when building without assertions.</p>
</li>
<li>
- <p>fuzz_server_header(): Fix compiler warning.</p>
+ <p>receive_encrypted_request_headers(): Improve a log message</p>
</li>
<li>
- <p>fuzz_client_header(): Fix compiler warning.</p>
+ <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>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.</p>
+ <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>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>
+ <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>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>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>

- Binderman</p>
+ <p>Add a "inactivity detection" mode Which can be useful for debugging purposes.</p>
</li>
<li>
- <p>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.
