Synopsis :

The remote Gentoo host is missing one or more security-related
patches.

Description :

The remote host is affected by the vulnerability described in GLSA-201206-02
(QtGui: User-assisted execution of arbitrary code)

An error in qtiffhandler.cpp could cause a buffer overflow.

Impact :

A remote attacker could entice a user to open a specially crafted TIFF
image with an application linked against QtGui, possibly resulting in
execution of arbitrary code with the privileges of the process or a
Denial of Service condition.

Workaround :

There is no known workaround at this time.

Solution :

All QtGui users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose '>=x11-libs/qt-gui-4.7.4-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.

Risk factor :

High / CVSS Base Score : 9.3
