    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
      # emerge --ask --oneshot --verbose ">=media-video/vlc-3.0.12.1"
