Comment 1 Andrej Nemec 2016-01-22 03:57:53 EST

Created privoxy tracking bugs for this issue:

Affects: fedora-all [bug 1300967]
Affects: epel-6 [bug 1300968]
Affects: epel-7 [bug 1300969]

Comment 2 Tomas Hoger 2016-05-23 17:07:05 EDT

Buffer over-read issue, possibly leading to crash.  The privoxy is only included in Red Hat Enterprise Linux 5, which is in Phase 3 of its life cycle, and is therefore not planned to have this issue corrected.
