Comment 1 Andrej Nemec 2016-01-22 09:08:02 UTC 
Created privoxy tracking bugs for this issue:

Affects: fedora-all [bug 1300973]
Affects: epel-6 [bug 1300974]
Affects: epel-7 [bug 1300975]
Comment 2 Tomas Hoger 2016-05-23 21:07:38 UTC 
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.
