Synopsis
========

A heap-based buffer overflow in e2fsprogs might allow local attackers
to execute arbitrary code.

Background
==========

e2fsprogs is a set of utilities for maintaining the ext2, ext3 and ext4
file systems.

Affected packages
=================

-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 sys-fs/e2fsprogs < 1.42.12 >= 1.42.12

Description
===========

A heap-based buffer overflow was discovered in openfs.c in the
libext2fs library in e2fsprogs.

Impact
======

A remote attacker could entice a user to use ext2fs library (for
example, fsck) on a specially crafted Ext2/3/4 file system possibly
resulting in the execution of arbitrary code with the privileges of the
process or a Denial of Service condition.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All e2fsprogs users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose ">=sys-fs/e2fsprogs-1.42.12"

References
