Synopsis
========

A vulnerability in e2fsprogs might allow an attacker to execute
arbitrary code.

Background
==========

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

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

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

It was discovered that e2fsprogs incorrectly handled certain ext4
partitions.

Impact

corrupted file system using e2fsck, possibly resulting in execution of
arbitrary code with the privileges of the process or a Denial of
Service condition.

Workaround
