"Privoxy Developers reports :

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. 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. CVE-2015-1381.

Fixed an 'invalid read' bug which could at least theoretically cause
Privoxy to crash. So far, no crashes have been observed.
CVE-2015-1382."
