Synopsis
========

Multiple buffer overflow vulnerabilities in gdk-pixbuf may allow remote
attackers to execute arbitrary code or cause Denial of Service.

Background
==========

gdk-pixbuf is an image loading library for GTK+.

Affected packages
=================

-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 x11-libs/gdk-pixbuf < 2.32.1 >= 2.32.1

Description
===========

Three heap-based buffer overflow vulnerabilities have been discovered
in gdk-pixbuf. Please review the CVE identifiers referenced below for
details.

Impact
======

A remote attacker could entice a user to open a specially crafted image
file with an application linked against gdk-pixbuf, 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 gdk-pixbuf users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose ">=x11-libs/gdk-pixbuf-2.32.1"

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