Severity:	normal
Title:	e2fsprogs: Heap-based buffer overflow
Date:	01/01/2017
Bugs:	#538930
ID:	201701-06

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	Architecture(s)
sys-fs/e2fsprogs	< 1.42.12	>= 1.42.12	All supported architectures

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"
