(X.org, XFree86: Integer and stack overflows in libXpm)

    Chris Evans has discovered multiple integer and stack overflow
    vulnerabilities in the X Pixmap library, libXpm, which is a part of the
    X Window System. These overflows can be exploited by the execution of a
    malicious XPM file, which can crash applications that are dependent on
    libXpm.
  
Impact :

    A carefully-crafted XPM file could crash applications that are linked
    against libXpm, potentially allowing the execution of arbitrary code
    with the privileges of the user running the application.
  
Workaround :

    There is no known workaround at this time."
