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

-------------------------------------------------------------------

1 media-libs/imlib2 < 1.4.2-r1 >= 1.4.2-r1

 

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"
