"The remote NewStart CGSL host, running version CORE 5.04 / MAIN 5.04, has gcc packages installed that are affected by a
vulnerability:

  - Under certain circumstances, the ix86_expand_builtin
    function in i386.c in GNU Compiler Collection (GCC)
    version 4.6, 4.7, 4.8, 4.9, 5 before 5.5, and 6 before
    6.4 will generate instruction sequences that clobber the
    status flag of the RDRAND and RDSEED intrinsics before
    it can be read, potentially causing failures of these
    instructions to go unreported. This could potentially
    lead to less randomness in random number generation.
    (CVE-2017-11671)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
