QtCore, QtGui: Multiple vulnerabilities

Background

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

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.
