The remote host is missing an update to qt-x11-free announced via advisory DSA 1200-1. 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. https://secure1.securityspace.com/smysecure/catid.html?in=DSA%201200-1
