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	Architecture(s)
x11-libs/gdk-pixbuf	< 2.32.1	>= 2.32.1	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:

      # 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.
