qt-x11-free - integer overflow

An integer overflow has been found in the pixmap handling routines in
the Qt GUI libraries. This could allow an attacker to cause a denial of
service and possibly execute arbitrary code by providing a specially
crafted image file and inducing the victim to view it in an application
based on Qt.

For the stable distribution (sarge), this problem has been fixed in
version 3:3.3.4-3sarge1.

For the unstable distribution (sid), this problem has been fixed in
versions 3:3.3.7-1 and 4.2.1-1.

We recommend that you upgrade your qt-x11-free packages.
