Synopsis
========
Multiple vulnerabilities have been discovered in QtCore and QtGui,
possibly resulting in execution of arbitrary code, Denial of Service,
or man-in-the-middle attacks.

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

Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 dev-qt/qtcore < 4.8.4-r2 >= 4.8.4-r2
2 dev-qt/qtgui < 4.8.4-r1 >= 4.8.4-r1
-------------------------------------------------------------------
2 affected packages

Description
===========
Multiple vulnerabilities have been discovered in QtCore and QtGui.
Please review the CVE identifiers referenced below for details.

Impact
======
A remote attacker could entice a user to open a specially crafted file
with an application linked against QtCore or QtGui, possibly resulting
in execution of arbitrary code with the privileges of the process or a
Denial of Service condition. Furthermore, a remote attacker might
employ a specially crafted certificate to conduct man-in-the-middle
attacks on SSL connections.

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-4.8.4-r2"

All QtGui users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-qt/qtgui-4.8.4-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.
