"The remote NewStart CGSL host, running version CORE 5.05 / MAIN 5.05, has SDL packages installed that are affected by a
vulnerability:

  - A flaw was found with the RHSA-2019:3950 erratum, where
    it did not fix the CVE-2019-13616 SDL vulnerability.
    This issue only affects Red Hat SDL packages, SDL
    versions through 1.2.15 and 2.x through 2.0.9 has a
    heap-based buffer overflow flaw while copying an
    existing surface into a new optimized one, due to a lack
    of validation while loading a BMP image, is possible. An
    application that uses SDL to parse untrusted input files
    may be vulnerable to this flaw, which could allow an
    attacker to make the application crash or execute code.
    (CVE-2019-14906)

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