Title:	Imlib2: User-assisted execution of arbitrary code
Date:	12/23/2008
Bugs:	#248057
ID:	200812-23

Synopsis

A buffer overflow vulnerability has been discovered in Imlib2.

Background

Imlib2 is replacement library from the Enlightenment project for libraries like libXpm.

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
media-libs/imlib2	< 1.4.2-r1	>= 1.4.2-r1	All supported architectures

Description

Julien Danjou reported a pointer arithmetic error and a heap-based buffer overflow within the load() function of the XPM image loader.

Impact

A remote attacker could entice a user to process a specially crafted XPM image, possibly resulting in the remote execution of arbitrary code with the privileges of the user running the application, or a Denial of Service.

Workaround

There is no known workaround at this time.

Resolution

All Imlib2 users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=media-libs/imlib2-1.4.2-r1"
