53.0.282019/01/01
Announcing Privoxy 3.0.28 stable
Privoxy 3.0.27 stable scales better in multi-user environments
and brings a couple of tuning directives.
Privoxy 3.0.28 stable fixes two regressions introduced in 3.0.27.
ChangeLog for Privoxy 3.0.28
- Bug fixes for regressions in 3.0.27:
- Fixed misplaced parentheses.
Reported by David Binderman.
- Changed two regression tests to depend on config directive
enable-remote-toggle instead of FEATURE_TOGGLE.
--------------------------------------------------------------------
ChangeLog for Privoxy 3.0.27
--------------------------------------------------------------------
- Add a receive-buffer-size directive which can be used to
set the size of the previously statically allocated buffer
in handle_established_connection().
Increasing the buffer size increases Privoxy's memory usage but
can lower the number of context switches and thereby reduce the
CPU usage and potentially increase the throughput.

63.0.262016/08/30
Announcing Privoxy 3.0.26 stable
Privoxy 3.0.26 stable is a bug-fix release for the previously
released 3.0.25 beta which introduced client-specific tags and
included a couple of minor improvements.
- Fixed crashes with "listen-addr :8118" (SF Bug #902).
The regression was introduced in 3.0.25 beta and reported
by Marvin Renich in Debian bug #834941.
- General improvements:
- Log when privoxy is toggled on or off via cgi interface.
- Highlight the "Info: Now toggled " on/off log message
in the Windows log viewer.
- Highlight the loading actions/filter file log message
in the Windows log viewer.
- Mention client-specific tags on the toggle page as a
potentionally more appropriate alternative.
- Documentation improvements:
- Update download section on the homepage.
The downloads are available from the website now.
- Add sponsor FAQ.

73.0.252016/06/04
Announcing Privoxy 3.0.25 beta
Privoxy 3.0.25 beta introduces client-specific tags and includes
a couple of minor improvements. It will be followed by a stable
release in the near future.
- 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.
- Fixed two buffer-overflows in the (deprecated) static
pcre code. These bugs are not considered security issues
as the input is trusted.
Found with afl-fuzz and ASAN.
- 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.

83.0.242016/01/28
Announcing Privoxy 3.0.24 stable
Privoxy 3.0.24 stable contains a couple of new features but is
mainly a bug-fix release. Two of the fixed bugs are security issues
and may be used to remotely trigger crashes on platforms that
carefully check memory accesses (most don't).
- Security fixes (denial of service):
- Prevent invalid reads in case of corrupt chunk-encoded content.
CVE-2016-1982. Bug discovered with afl-fuzz and AddressSanitizer.
- Remove empty Host headers in client requests.
Previously they would result in invalid reads. CVE-2016-1983.
Bug discovered with afl-fuzz and AddressSanitizer.
- 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 M端ller and G4JC.
- Fixed buffer scaling in execute_external_filter() that could lead
to crashes. Submitted by Yang Xia in #892.
- Fixed crashes when executing external filters on platforms like
Mac OS X. Reported by Jonathan McKenzie on ijbswa-users@.

93.0.192011/12/27
Announcing Privoxy v.3.0.19 stable
This is a bug-fix release for the previously released
Privoxy 3.0.18. One of the fixes addresses a security issue.
--------------------------------------------------------------------
*** Version 3.0.19 Stable ***
- Bug fixes:
- Prevent a segmentation fault when de-chunking buffered content.
It could be triggered by malicious web servers if Privoxy was
configured to filter the content and running on a platform
where SIZE_T_MAX isn't larger than UINT_MAX, which probably
includes most 32-bit systems. On those platforms, all Privoxy
versions before 3.0.19 appear to be affected.
To be on the safe side, this bug should be presumed to allow
code execution as proving that it doesn't seems unrealistic.
- Do not expect a response from the SOCKS4/4A server until it
got something to respond to. This regression was introduced
in 3.0.18 and prevented the SOCKS4/4A negotiation from working.
Reported by qqqqqw in #3459781.
- General improvements:

103.0.182011/11/21
Announcing Privoxy v.3.0.18 stable
This is mainly a bug-fix release for the previously released
Privoxy 3.0.17. One of the fixes addresses a security issue.
*** Version 3.0.18 stable ***
- Bug fixes:
- If the redirect URL contains characters RFC 3986 doesn't permit,
they are (re)encoded. Not doing this makes Privoxy versions from
3.0.5 to 3.0.17 susceptible to HTTP response splitting (CWE-113)
attacks if the +fast-redirects{check-decoded-url} action is used.
- Fix a logic bug that could cause Privoxy to reuse a server
socket after it got tainted by a server-header-tagger-induced
block that was triggered before the whole server response had
been read. If keep-alive was enabled and the request following
the blocked one was to the same host and using the same forwarding
settings, Privoxy would send it on the tainted server socket.
While the server would simply treat it as a pipelined request,
Privoxy would later on fail to properly parse the server's
response as it would try to parse the unread data from the
first response as server headers for the second one.

113.0.172010/11/15
Announcing Privoxy v.3.0.17 stable
This is mainly a bug-fix release for the previously released Privoxy 3.0.16.
It contains fixes for two bugs that could cause connections to hang under
certain circumstances when keep-alive support was enabled, until they timed
out or where closed by the server.
See http://www.privoxy.org/3.0.17/user-manual/whatsnew.html for details.
*** Version 3.0.17 Stable ***
- Fixed last-chunk-detection for responses where the content was small
enough to be read with the body, causing Privoxy to wait for the
end of the content until the server closed the connection or the
request timed out. Reported by "Karsten" in #3028326.
- Responses with status code 204 weren't properly detected as body-less
like RFC2616 mandates. Like the previous bug, this caused Privoxy to
wait for the end of the content until the server closed the connection
or the request timed out. Fixes #3022042 and #3025553, reported by a
user with no visible name. Most likely also fixes a bunch of other
AJAX-related problem reports that got closed in the past due to
insufficient information and lack of feedback.
- Fixed an ACL bug that made it impossible to build a blacklist.
