|Bugzilla:||889935: CVE-2012-5667 grep: Integer overflow leading to heap-based buffer-overflow when reading large lines|
An integer overflow flaw, leading to a heap-based buffer overflow, was found in the way grep parsed large lines of data. An attacker able to trick a user into running grep on a specially crafted data file could use this flaw to crash grep or, potentially, execute arbitrary code with the privileges of the user running grep.
This issue did not affect the version of grep as shipped with Red Hat Enterprise Linux 5.
