    Synopsis
    ========

    RealPlayer and Helix Player are vulnerable to a buffer overflow that
    could lead to remote execution of arbitrary code.

    Background
    ==========

    RealPlayer is a multimedia player capable of handling multiple
    multimedia file formats. Helix Player is the Open Source version of
    RealPlayer.

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

        -------------------------------------------------------------------
         Package / Vulnerable / Unaffected
        -------------------------------------------------------------------
      1 media-video/realplayer < 10.0.4 >= 10.0.4
      2 media-video/helixplayer < 1.0.4 >= 1.0.4
        -------------------------------------------------------------------
         2 affected packages on all of their supported architectures.
        -------------------------------------------------------------------

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

    Piotr Bania has discovered a buffer overflow vulnerability in
    RealPlayer and Helix Player when processing malicious RAM files.

    Impact
    ======

    By enticing a user to play a specially crafted RAM file an attacker
    could execute arbitrary code with the permissions of the user running
    the application.

    Workaround
    ==========

    There is no known workaround at this time.

    Resolution
    ==========

    All RealPlayer users should upgrade to the latest version:

        # emerge --sync
        # emerge --ask --oneshot --verbose ">=media-video/realplayer-10.0.4"

    All Helix Player users should upgrade to the latest version:

        # emerge --sync
        # emerge --ask --oneshot --verbose ">=media-video/helixplayer-1.0.4"
