http://security.gentoo.org/

Severity:	normal
Title:	GEGL: User-assisted execution of arbitrary code
Date:	10/06/2013
Bugs:	#442016
ID:	201310-05

Synopsis

A vulnerability in GEGL might allow a remote attacker to execute arbitrary code.

Background

GEGL is a graph-based image processing framework.

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
media-libs/gegl	< 0.2.0-r2	>= 0.2.0-r2	All supported architectures

Description

Multiple integer overflows in GEGL may cause a heap-based buffer overflow.

Impact

A remote attacker could entice a user to open a specially crafted PPM image using an application linked against GEGL, 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 gegl users should upgrade to the latest version:

      # emerge --sync
      # emerge --ask --oneshot --verbose ">=media-libs/gegl-0.2.0-r2"

Packages which depend on this library may need to be recompiled. Tools such as revdep-rebuild may assist in identifying some of these packages.
