1.  Gentoo Linux Security Advisory

Version Information

Advisory Reference GLSA 201206-02 / qt-gui
Release Date June 03, 2012
Latest Revision June 03, 2012: 1
Impact normal
Exploitable remote
Package Vulnerable versions Unaffected versions Architecture(s)
x11-libs/qt-gui < 4.7.4-r1 >= 4.7.4-r1 All supported architectures

Related bugreports: #384089


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

2.  Impact Information


QtGui is a module for the Qt toolkit.


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


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.

3.  Resolution Information


There is no known workaround at this time.


All QtGui users should upgrade to the latest version:

Code Listing 3.1: Resolution

  # 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.
