-CLASS="emphasis"
-><I

+ <p><span class="APPLICATION">Privoxy 3.0.32</span> fixes multiple DoS issues and a couple of other bugs. The issues

+ <p>Changes in <span class="APPLICATION">Privoxy 3.0.32</span> stable:</p>
+ <ul>
+ <li>
+ <p>Security/Reliability:</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>
+ </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>
+ </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>
+ </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>
+ </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>
+ </li>
+ </ul>
+ </li>
+ <li>
+ <p>Bug fixes:</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>
+ </li>
+ <li>
+ <p>decompress_iob(): Prevent reading of uninitialized data. Reported by: Joshua Rogers (Opera).</p>
+ </li>
+ <li>
+ <p>decompress_iob(): Don't advance cur past eod when looking for the end of the file name and comment.</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>
+ </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>
+ </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>
+ </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>
+ </li>
+ <li>
+ <p>Respect DESTDIR when considering whether or not to install config files with ".new" extension.</p>
+ </li>
+ <li>
+ <p>OpenSSL ssl_store_cert(): Fix two error messages.</p>
+ </li>
+ <li>
+ <p>Fix a couple of format specifiers.</p>
+ </li>
+ <li>
+ <p>Silence compiler warnings when compiling with NDEBUG.</p>
+ </li>
+ <li>
+ <p>fuzz_server_header(): Fix compiler warning.</p>
+ </li>
+ <li>
+ <p>fuzz_client_header(): Fix compiler warning.</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>
+ </li>
+ </ul>
+ </li>
+ <li>
+ <p>General improvements:</p>
+ <ul>
+ <li>
+ <p>Log the TLS version and the the cipher when debug 2 is enabled.</p>
+ </li>
+ <li>
+ <p>ssl_send_certificate_error(): Respect HEAD requests by not sending a body.</p>
+ </li>
+ <li>
+ <p>ssl_send_certificate_error(): End the body with a single new line.</p>
+ </li>
+ <li>
+ <p>serve(): Increase the chances that the host is logged when closing a server socket.</p>
+ </li>
+ <li>
+ <p>handle_established_connection(): Add parentheses to clarify an expression Suggested by: David
+ Binderman</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.
+ Previously serve() relied on CSP_FLAG_SERVER_CONTENT_LENGTH_SET and CSP_FLAG_CHUNKED being unset. Inspired
+ by a patch from Joshua Rogers (Opera).</p>
+ </li>
+ <li>
+ <p>decompress_iob(): Add periods to a couple of log messages</p>
+ </li>
+ <li>
+ <p>Terminate the body of the HTTP snipplets with a single new line instead of "\r\n".</p>
+ </li>
+ <li>
+ <p>configure: Add --with-assertions option and only enable assertions when it is used</p>
+ </li>
+ <li>
+ <p>windows build: Use --with-brotli and --with-mbedtls by default and enable dynamic error checking.</p>
+ </li>
+ <li>
+ <p>gif_deanimate(): Confirm we've got an image before trying to write it Saves a pointless buf_copy()
+ call.</p>
+ </li>
+ <li>
+ <p>OpenSSL ssl_store_cert(): Remove a superfluous space before the serial number.</p>
+ </li>
+ </ul>
+ </li>
+ <li>
+ <p>Action file improvements:</p>
+ <ul>
+ <li>
+ <p>Disable fast-redirects for .golem.de/</p>
+ </li>
+ <li>
+ <p>Unblock requests to adri*.</p>
+ </li>
+ <li>

+ </ul>
+ </li>
+ <li>
+ <p>Filter file improvements:</p>
+ <ul>
+ <li>
+ <p>Make the second pcrs job of the img-reorder filter greedy again. The ungreedy version broke the img tags
+ on: https://bulk.fefe.de/scalability/.</p>
+ </li>
+ </ul>
+ </li>
+ <li>
+ <p>Privoxy-Log-Parser:</p>
+ <ul>
+ <li>
+ <p>Highlight a few more messages.</p>

+ <p>Clarify that 'debug 32768' should be used in addition to the other debug directives when reporting
+ problems.</p>
+ </li>
+ <li>
+ <p>Add a 'Third-party licenses and copyrights' section to the user manual.</p>

+ <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>
