"According to its self-reported version number, the Symantec Messaging
Gateway (SMG) running on the remote host is 10.x prior to 10.6.2. It
is, therefore, affected by multiple 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)

  - An information disclosure vulnerability exists in the
    charting component in the control center due to improper
    sanitization of user-supplied input submitted for
    charting requests. An authenticated, remote attacker can
    exploit this, via a directory traversal attack, to
    disclose arbitrary files or directory contents.
    (CVE-2016-5312)

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