Subject:                OpenServer 5.0.6 OpenServer 5.0.7 OpenServer 6.0.0 : 
GTK+ gdk-pixbuf XPM Loader Heap Overflow Vulnerability
Advisory number:        SCOSA-2006.8
Issue date:             2006 January 13
Cross reference:        fz533256
                        CVE-2005-3186
______________________________________________________________________________


1. Problem Description

        Integer overflow in the GTK+ gdk-pixbuf XPM image rendering
        library in GTK+ allows attackers to execute arbitrary code via
        an XPM file with a number of colors that causes insufficient
        memory to be allocated, which leads to a heap-based buffer
        overflow.

        The Common Vulnerabilities and Exposures project (cve.mitre.org)
        has assigned the name CVE-2005-3186 to this issue.
