QtCore: Denial of service

Background

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

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.
