1.  Gentoo Linux Security Advisory

Version Information

Advisory Reference GLSA 201206-20 / gdk-pixbuf
Release Date June 23, 2012
Latest Revision June 23, 2012: 1
Impact normal
Exploitable remote
Package Vulnerable versions Unaffected versions Architecture(s)

Related bugreports: #373999, #412033


Multiple vulnerabilities in gdk-pixbuf may create a Denial of Service condition.

2.  Impact Information


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


Two vulnerabilities have been found in gdk-pixbuf:

  • The "gdk_pixbuf__gif_image_load()" function in io-gif.c fails to properly handle certain return values from subroutines (CVE-2011-2485).
  • The "read_bitmap_file_data()" function in io-xbm.c contains an integer overflow error (CVE-2012-2370).


A remote attacker could entice a user to open a specially crafted image in an application linked against gdk-pixbuf, possibly resulting in Denial of Service.

3.  Resolution Information


There is no known workaround at this time.


All gdk-pixbuf users should upgrade to the latest version:

Code Listing 3.1: Resolution

  # emerge --sync
  # emerge --ask --oneshot --verbose ">=x11-libs/gdk-pixbuf-2.24.1-r1"

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