"The version of Symantec Endpoint Protection (SEP) Client installed on
the remote Windows host is 12.1.x prior to 12.1.6 MP6 or else
12.1.6 MP5 without a hotfix. It is, therefore, affected by multiple
denial of service vulnerabilities :

  - A denial of service vulnerability exists in the
    decomposer engine due to an out-of-bounds read error
    that occurs when decompressing RAR archives. An
    unauthenticated, remote attacker can exploit this, via a
    specially crafted RAR file, to crash the application.
    (CVE-2016-5309)

  - A denial of service vulnerability exists in the
    decomposer engine due to memory corruption issue that
    occurs when decompressing RAR archives. An
    unauthenticated, remote attacker can exploit this, via a
    specially crafted RAR file, to crash the application.
    (CVE-2016-5310)

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