CVE-2011-2689  (opens in a new tab)
CWE-400  (opens in a new tab)

How to fix?

Upgrade RHEL:6 perf to version 0:2.6.32-131.12.1.el6 or higher.
This issue was patched in RHSA-2011:1189.

NVD Description

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

The gfs2_fallocate function in fs/gfs2/file.c in the Linux kernel before 3.0-rc1 does not ensure that the size of a chunk allocation is a multiple of the block size, which allows local users to cause a denial of service (BUG and system crash) by arranging for all resource groups to have too little free space.
