    Synopsis
    ========

    A new vulnerability has been discovered in libXpm, which is included in
    OpenMotif and LessTif, that can potentially lead to remote code
    execution.

    Background
    ==========

    LessTif is a clone of OSF/Motif, which is a standard user interface
    toolkit available on Unix and Linux. OpenMotif also provides a free
    version of the Motif toolkit for open source applications.

    Affected packages
    =================

        -------------------------------------------------------------------
         Package / Vulnerable / Unaffected
        -------------------------------------------------------------------
      1 x11-libs/openmotif < 2.2.3-r3 >= 2.2.3-r3
                                                             *>= 2.1.30-r9
      2 x11-libs/lesstif < 0.94.0-r2 >= 0.94.0-r2
        -------------------------------------------------------------------
         2 affected packages on all of their supported architectures.
        -------------------------------------------------------------------

    Description
    ===========

    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.

    Resolution
    ==========

    All OpenMotif users should upgrade to an unaffected version:

        # emerge --sync
        # emerge --ask --oneshot --verbose x11-libs/openmotif

    All LessTif users should upgrade to the latest version:

        # emerge --sync
        # emerge --ask --oneshot --verbose ">=x11-libs/lesstif-0.94.0-r2"
