  <title>GTK+ 2, GdkPixbuf: Multiple XPM decoding vulnerabilities</title>
  <synopsis>
    The GdkPixbuf library, that is also included in GTK+ 2, contains
    vulnerabilities that could lead to a Denial of Service or the execution of
    arbitrary code.

    <p>
    GTK+ (the GIMP Toolkit) is a toolkit for creating graphical user
    interfaces. The GdkPixbuf library provides facilities for image
    handling. It is available as a standalone library and also packaged
    with GTK+ 2.

    <p>
    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).
    </p>
  </description>
  <impact type="normal">
    <p>
    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.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All GTK+ 2 users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose x11-libs/gtk+</code>
    <p>
    All GdkPixbuf users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose "&gt;=media-libs/gdk-pixbuf-0.22.0-r5"</code>
  </resolution>
