Synopsis
========

Multiple vulnerabilities have been found in QtGui allowing remote
attackers to execute arbitrary code or cause Denial of Service.

Background
==========

QtGui is the GUI module and platform plugins for the Qt framework

Affected packages
=================

    -------------------------------------------------------------------
     Package              /     Vulnerable     /            Unaffected
    -------------------------------------------------------------------
  1  dev-qt/qtgui                < 5.4.1-r1                 *>= 4.8.7
                                                         *>= 4.8.6-r4
                                                          >= 5.4.1-r1

Description
===========

Multiple buffer overflow vulnerabilities have been discovered in QtGui.
It is possible for remote attackers to construct specially crafted BMP,
ICO, or GIF images that lead to buffer overflows. After successfully
overflowing the buffer the remote attacker can then cause a Denial of
Service or execute arbitrary code.

Impact
======

A remote attacker could possibly execute arbitrary code or cause Denial
of Service.

Workaround
==========

There is no known work around at this time.

Resolution
==========

All QtGui 4.8 users should upgrade to the latest version:

  # emerge --sync
  # emerge --ask --oneshot --verbose ">=dev-qt/qtgui-4.8.6-r4"

All QtGui 5.4 users should upgrade to the latest version:

  # emerge --sync
  # emerge --ask --oneshot --verbose ">=dev-qt/qtgui-5.4.1-r1"
