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.
