Synopsis

========

 

Two vulnerabilities in Imlib 2 may allow for the execution of arbitrary

code.

 

Background

==========

 

Imlib 2 is an advanced replacement library for libraries like libXpm.

 

Affected packages

=================

 

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

Package / Vulnerable / Unaffected

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

1 media-libs/imlib2 < 1.4.0-r1 >= 1.4.0-r1

 

Description

===========

 

Stefan Cornelius (Secunia Research) reported two boundary errors in

Imlib2:

 

* One of them within the load() function in the file

src/modules/loaders/loader_pnm.c when processing the header of a PNM

image file, possibly leading to a stack-based buffer overflow.

 

* The second one within the load() function in the file

src/modules/loader_xpm.c when processing an XPM image file, possibly

leading to a stack-based buffer overflow.

 

Impact

======

 

A remote attacker could entice a user to open a specially crafted PNM

or XPM image, possibly resulting in the execution of arbitrary code

with the rights of the user running the application using Imlib 2.

 

Workaround

==========

 

There is no known workaround at this time.

 

Resolution

==========

 

All Imlib 2 users should upgrade to the latest version:

 

# emerge --sync

# emerge --ask --oneshot --verbose ">=media-libs/imlib2-1.4.0-r1"
