(OpenMotif, LessTif: New libXpm buffer overflows)

    Chris Gilbert discovered potentially exploitable buffer overflow
    cases in libXpm that weren't fixed in previous libXpm security
    advisories.
  
Impact :

    A carefully-crafted XPM file could crash applications making use
    of the OpenMotif or LessTif toolkits, 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."
