Gentoo Linux Security Advisory

Title: gdk-pixbuf: Multiple Vulnerabilities (GLSA 201512-05)
Severity: normal
Exploitable: remote
Date: December 21, 2015
Bug(s): #556314, #562878, #562880
ID: 201512-05

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: x11-libs/gdk-pixbuf
Vulnerable: < 2.32.1
Unaffected: >= 2.32.1
Architectures: All supported architectures


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:
Code:
# 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.
