NVD Description

Note: Versions mentioned in the description apply only to the upstream grep package and not the grep package as distributed by Centos. See How to fix? for Centos:6 relevant fixed versions and status.

Multiple integer overflows in GNU Grep before 2.11 might allow context-dependent attackers to execute arbitrary code via vectors involving a long input line that triggers a heap-based buffer overflow.
