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.
