Comment 4 Stefan Cornelius 2015-10-22 12:33:59 UTC 
Fedora / RHEL7 are affected in the same way - segfault.

RHEL6 is affected, too, but in a different manner: the process gets into an infinite (or at least very long, >60s) loop. The patch linked in comment #0 does not fix this in RHEL6.
Comment 5 Stefan Cornelius 2015-10-23 12:55:03 UTC 
The infinite loop in RHEL6 is annoying but shouldn't qualify as security issue.
