Created icecast tracking bugs for this issue

Affects: fedora-all [bug 768175]
Affects: epel-5 [bug 768176]

Comment 2 Vincent Danen 2012-06-15 18:24:56 UTC

This is corrected in upstream 2.3.3 version (released June 11th):

http://www.icecast.org/

https://bugzilla.novell.com/show_bug.cgi?id=862096 notes the icecast-2.3.2-CVE-2011-4612.diff introdces a use-after-free flaw and should be removed (since the issue was fixed upstream). I could not find this patch in Fedora or EPEL 6.

EPEL 6 is missing from the trackers here ... but it seems to have the fixed version now, so I will not file one.
