Описание
Integer overflow in the xfs_acl_from_disk function in fs/xfs/xfs_acl.c in the Linux kernel before 3.1.9 allows local users to cause a denial of service (panic) via a filesystem with a malformed ACL, leading to a heap-based buffer overflow.
Отчет
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.
