(GTK+ 2, GdkPixbuf: Multiple XPM decoding vulnerabilities)

    iDEFENSE reported a possible heap overflow in the XPM loader
    (CVE-2005-3186). Upon further inspection, Ludwig Nussel discovered two
    additional issues in the XPM processing functions : an integer overflow
    (CVE-2005-2976) that affects only gdk-pixbuf, and an infinite loop
    (CVE-2005-2975).
  
Impact :

    Using a specially crafted XPM image an attacker could cause an
    affected application to enter an infinite loop or trigger the
    overflows, potentially allowing the execution of arbitrary code.
  
Workaround :

    There is no known workaround at this time."
