    Synopsis
    ========

    Two vulnerabilities have been found in MPlayer which could lead to the
    remote execution of arbitrary code.

    Background
    ==========

    MPlayer is a media player capable of handling multiple multimedia file
    formats.

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

        -------------------------------------------------------------------
         Package / Vulnerable / Unaffected
        -------------------------------------------------------------------
      1 media-video/mplayer < 1.0_pre6-r4 >= 1.0_pre6-r4

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

    Heap overflows have been found in the code handling RealMedia RTSP and
    Microsoft Media Services streams over TCP (MMST).

    Impact
    ======

    By setting up a malicious server and enticing a user to use its
    streaming data, a remote attacker could possibly execute arbitrary code
    on the client computer with the permissions of the user running
    MPlayer.

    Workaround
    ==========

    There is no known workaround at this time.

    Resolution
    ==========

    All MPlayer users should upgrade to the latest version:

        # emerge --sync
        # emerge --ask --oneshot --verbose ">=media-video/mplayer-1.0_pre6-r4"
