Gentoo Linux Security Advisory

Title: GEGL: User-assisted execution of arbitrary code (GLSA 201310-05)
Severity: normal
Exploitable: remote
Date: October 06, 2013
Bug(s): #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: media-libs/gegl
Vulnerable: < 0.2.0-r2
Unaffected: >= 0.2.0-r2
Architectures: 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:
Code:
# 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.
