GLSA-200712-13 : E2fsprogs: Multiple buffer overflows

This script is Copyright (C) 2007-2014 Tenable Network Security, Inc.


Synopsis :

The remote Gentoo host is missing one or more security-related
patches.

Description :

The remote host is affected by the vulnerability described in GLSA-200712-13
(E2fsprogs: Multiple buffer overflows)

Rafal Wojtczuk (McAfee AVERT Research) discovered multiple integer
overflows in libext2fs, that are triggered when processing information
from within the file system, resulting in heap-based buffer overflows.

Impact :

An attacker could entice a user to process a specially-crafted ext2 or
ext3 file system image (with tools linking against libext2fs, e.g.
fsck, forensic tools or Xen's pygrub), possibly resulting in the
execution of arbitrary code with the privileges of the user running the
application.

Workaround :

There is no known workaround at this time.

Solution :

All E2fsprogs users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose '>=sys-fs/e2fsprogs-1.40.3'

Risk factor :

Medium / CVSS Base Score : 5.8
