Description Eugene Teo (Security Response) 2012-01-11 12:17:06 UTC 
Commit ef14f0c1578dce4b688726eb2603e50b62d6665a introduced an integer overflow in the ACL handling code, which could further lead to heap-based buffer overflow via a crafted filesystem.

Upstream commits:
http://git.kernel.org/linus/fa8b18edd752a8b4e9d1ee2cd615b82c93cf8bba
http://git.kernel.org/linus/093019cf1b18dd31b2c3b77acce4e000e2cbc9ce

Both commits are needed to fix the vulnerability.

The vulnerability seems to first appear in 2.6.32-rc1.  3.2 contains only the
first commit.

Acknowledgements:

Red Hat would like to thank Wang Xi for reporting this issue.

Comment 7 Eugene Teo (Security Response) 2012-03-07 03:00:44 UTC 
Statement:

This issue did not affect the Linux kernel as shipped with Red Hat Enterprise Linux 4 as it did not have support for the XFS file system. It did not affect the Linux kernel as shipped with Red Hat Enterprise Linux 5 as it did not backport the upstream commit ef14f0c1 that introduced the vulnerability. This has been addressed in Red Hat Enterprise Linux 6 and Red Hat Enterprise MRG via https://rhn.redhat.com/errata/RHSA-2012-0350.html, and https://rhn.redhat.com/errata/RHSA-2012-0333.html.
