Description Tomas Hoger 2012-02-24 09:25:11 UTC 
+++ This bug was initially created as a clone of Bug #797094 +++

Description of problem:
Upstream has fixed couple of unbound alloca uses which can lead to program crashes if excessively long inputs are passed to certain functions.

RHEL-5 glibc version does not seem to have affected nscd_getserv_r, but the glob and getaddrinfo issues should apply.
