Subject: 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 project pcrs (not to be confused with pcre) which is no longer maintained.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.
