QtGui: User-assisted execution of arbitrary code — GLSA 201206-02

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

Affected Packages

x11-libs/qt-gui on all architectures
Affected versions < 4.7.4-r1
Unaffected versions >= 4.7.4-r1

Background

QtGui is a module for the Qt toolkit.

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.
