    Synopsis
    ========

    A buffer overflow in VLC might allow remote attacker(s) to execute
    arbitrary code.

    Background
    ==========

    VLC is a cross-platform media player and streaming server.

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

    -------------------------------------------------------------------
    Package / Vulnerable / Unaffected
    -------------------------------------------------------------------
    1 media-video/vlc < 3.0.12.1 >= 3.0.12.1

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

    VLC was found to have a buffer overflow when handling crafted MKV
    files.

    Impact
    ======

    A remote attacker could entice a user to open a specially crafted MKV
    file using VLC possibly resulting in execution of arbitrary code with
    the privileges of the process or a Denial of Service condition.

    Workaround
    ==========

    There is no known workaround at this time.

    Resolution
    ==========

    All VLC users should upgrade to the latest version:

    # emerge --sync
