Comment 3 Tomas Hoger 2008-02-13 12:50:28 UTC 
Due to minimal impact of this flaw (temporary DoS by high CPU usage) and low
likelihood of this problem being exposed in a way that would allow trust
boundary crossing, we currently do not plan to backport fix for this issue to
versions of gd shipped in current versions of Red Hat Enterprise Linux.
