Re: CVE request for Privoxy

Privoxy 3.0.23 contains fixes for the following security issues:

- Fixed a DoS issue in case of client requests with incorrect
 chunk-encoded body. When compiled with assertions enabled
 (the default) they could previously cause Privoxy to abort().
 Reported by Matthew Daley.
 http://ijbswa.cvs.sourceforge.net/viewvc/ijbswa/current/jcc.c?r1=1.433&r2=1.434

Use CVE-2015-1380.

- Fixed multiple segmentation faults and memory leaks in the
 pcrs code. This fix also increases the chances that an invalid
 pcrs command is rejected as such. Previously some invalid commands
 would be loaded without error. Note that Privoxy's pcrs sources
 (action and filter files) are considered trustworthy input and
 should not be writable by untrusted third-parties.
 http://ijbswa.cvs.sourceforge.net/viewvc/ijbswa/current/pcrs.c?r1=1.46&r2=1.47

Use CVE-2015-1381.

- Fixed an 'invalid read' bug which could at least theoretically
 cause Privoxy to crash.
 http://ijbswa.cvs.sourceforge.net/viewvc/ijbswa/current/parsers.c?r1=1.297&r2=1.298

Use CVE-2015-1382.

Please assign CVEs for them.

The second issue could potentially affect other programs that use pcrs.c,
but I'm not aware of any that do. Privoxy imported the file from the upstream
project pcrs (not to be confused with pcre) which is no longer maintained.

The last two issues were partially discovered with afl-fuzz.
