    Synopsis
    ========
    
    A buffer overflow in VLC might allow local or 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              < 3.0.10                  >= 3.0.10
    
    Description
    ===========
    
    A buffer overflow in DecodeBlock in sdl_image.c was discovered.
    
    Impact
    ======
    
    A remote user could craft a specifically crafted image file that could
    execute arbitrary code or cause denial of service.
    
    Workaround
    ==========
    
    The user should refrain from opening files from untrusted third parties
    or accessing untrusted remote sites (or disable the VLC browser
    plugins), until they upgrade.
    
    Resolution
    ==========
    
    All VLC users should upgrade to the latest version:
    
      # emerge --sync
      # emerge --ask --oneshot --verbose ">=media-video/vlc-3.0.10"
