    lua5.1 vulnerability
    ==========================================================================
    
    A security issue affects these releases of Ubuntu and its derivatives:
    
    - Ubuntu 14.04 LTS
    - Ubuntu 12.04 LTS
    
    Summary:
    
    Lua could be made to crash or run programs.
    
    Software Description:
    - lua5.1: Simple, extensible, embeddable programming language
    
    Details:
    
    It was discovered that Lua incorrectly handled certain vararg functions
    with a large number of fixed parameters. An attacker could use this issue
    to cause Lua applications to crash, resulting in a denial of service, or
    possibly execute arbitrary code.
