Synopsis
========

A vulnerability in QXmlSimpleReader class can be used to cause a Denial
of Service condition.

Background
==========

The Qt toolkit is a comprehensive C++ application development
framework.

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

    -------------------------------------------------------------------
     Package              /     Vulnerable     /            Unaffected
    -------------------------------------------------------------------
  1  dev-qt/qtcore               < 4.8.5-r1               >= 4.8.5-r1 

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

A vulnerability in QXmlSimpleReader's XML entity parsing has been
discovered.

Impact
======

A remote attacker could entice a user to open a specially crafted XML
file using an application linked against QtCore, possibly resulting in
Denial of Service.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All QtCore users should upgrade to the latest version:

  # emerge --sync
  # emerge --ask --oneshot --verbose ">=dev-qt/qtcore-4.8.5-r1"

Packages which depend on this library may need to be recompiled. Tools
such as revdep-rebuild may assist in identifying these packages.
