- <application>Privoxy 3.0.24</application> stable contains a couple
- of new features but is mainly a bug-fix release. Two of the fixed bugs
- are security issues (CVE requests pending) and may be used to remotely
- trigger crashes on platforms that carefully check memory accesses (most don't).

- Prevent invalid reads in case of corrupt chunk-encoded content.
- Bug discovered with afl-fuzz and AddressSanitizer.
+ Improve the handling of chunk-encoded responses by buffering the data
+ even if filters are disabled and properly keeping track of where the
+ various chunks are supposed to start and end. Previously Privoxy would
+ merely check the last bytes received to see if they looked like the
+ last-chunk. This failed to work if the last-chunk wasn't received in one
+ read and could also result in actual data being misdetected
+ as last-chunk.
+ Should fix: SF support request #1739.
+ Reported by: withoutname.

<para>
- Remove empty Host headers in client requests.
- Previously they would result in invalid reads.
- Bug discovered with afl-fuzz and AddressSanitizer.
+ ssl_send_certificate_error(): Don't crash if there's no certificate
+ information available. This is only relevant when Privoxy is built with
+ wolfSSL 5.0.0 or later (code not yet published). Earlier wolfSSL versions
+ or the other TLS backends don't seem to trigger the crash.

- Bug fixes:
+ General improvements:
<itemizedlist>
<listitem>
<para>
- 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.
+ Add a client-body-tagger action which creates tags based on
+ the content of the request body.
+ Sponsored by: Robert Klemme.
</para>
</listitem>
<listitem>
<para>
- Fixed buffer scaling in execute_external_filter() that could lead
- to crashes. Submitted by Yang Xia in #892.
+ When client-body filters are enabled, buffer the whole request
+ before opening a connection to the server.
+ Makes it less likely that the server connection times out
+ and we don't open a connection if the buffering fails anyway.
+ Sponsored by: Robert Klemme.
</para>
</listitem>
<listitem>
<para>
- Fixed crashes when executing external filters on platforms like
- Mac OS X. Reported by Jonathan McKenzie on ijbswa-users@.
+ Add periods to a couple of log messages.
</para>
</listitem>
<listitem>
<para>
- 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@.
+ accept_connection(): Add missing space to a log message.
</para>
</listitem>
<listitem>
<para>
- 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.
+ Initialize ca-related defaults with strdup_or_die() so errors
+ aren't silently ignored.
</para>
</listitem>
<listitem>
<para>
- 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.
+ make_path: Use malloc_or_die() in cases where allocation errors
+ were already fatal anyway.
</para>
</listitem>
<listitem>
<para>
- 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.
+ handle_established_connection(): Improve an error message slightly.
</para>
</listitem>
<listitem>
<para>
- Detect and reject parameters for parameter-less actions.
- Previously they were silently ignored.
+ receive_client_request(): Reject https URLs without CONNECT request.
</para>
</listitem>
<listitem>
<para>
- Fixed invalid reads in internal and outdated pcre code.
- Found with afl-fuzz and AddressSanitizer.
+ Include all requests in the statistics if mutexes are available.
+ Previously in case of reused connections only the last request got
+ counted. The statistics still aren't perfect but it's an improvement.
</para>
</listitem>
<listitem>
<para>
- Prevent invalid read when loading invalid action files.
- Found with afl-fuzz and AddressSanitizer.
+ Add read_socks_reply() and start using it in socks5_connect()
+ to apply the socket timeout more consistently.
</para>
</listitem>
<listitem>
<para>
- 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.
+ socks5_connect(): Deal with domain names in the socks reply
</para>
</listitem>
<listitem>
<para>
- 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.
+ Add a filter for bundeswehr.de that hides the cookie and
+ privacy info banner.

<para>
- 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.
+ Unblock .eff.org/.
</para>
</listitem>
<listitem>
<para>
- 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).
+ Stop unblocking .org/.*(image|banner) which appears to be too generous
+ The example URL http://www.gnu.org/graphics/gnu-head-banner.png is
+ already unblocked due to .gnu.org being unblocked.
</para>
