http://security.gentoo.org/

Severity:	normal
Title:	QtGui: User-assisted execution of arbitrary code
Date:	06/03/2012
Bugs:	#384089
ID:	201206-02

Synopsis

A buffer overflow in QtGui could result in execution of arbitrary code or Denial of Service.

Background

QtGui is a module for the Qt toolkit.

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
x11-libs/qt-gui	< 4.7.4-r1	>= 4.7.4-r1	All supported architectures

Description

An error in qtiffhandler.cpp could cause a buffer overflow.

Impact

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

      # emerge --sync
      # emerge --ask --oneshot --verbose ">=x11-libs/qt-gui-4.7.4-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.
