e2fsprogs: Arbitrary code execution

Background

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

Description

It was discovered that e2fsprogs incorrectly handled certain ext4 partitions.

Impact

A remote attacker could entice a user to process a specially crafted 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

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-1.45.4"
