The remote Redhat Enterprise Linux 6 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2017:0574 advisory.

    The gnutls packages provide the GNU Transport Layer Security (GnuTLS) library, which implements     cryptographic algorithms and protocols such as SSL, TLS, and DTLS.

    The following packages have been upgraded to a later upstream version: gnutls (2.12.23). (BZ#1321112,     BZ#1326073, BZ#1415682, BZ#1326389)

    Security Fix(es):

    * A denial of service flaw was found in the way the TLS/SSL protocol defined processing of ALERT packets     during a connection handshake. A remote attacker could use this flaw to make a TLS/SSL server consume an     excessive amount of CPU and fail to accept connections form other clients. (CVE-2016-8610)

    * Multiple flaws were found in the way gnutls processed OpenPGP certificates. An attacker could create     specially crafted OpenPGP certificates which, when parsed by gnutls, would cause it to crash.
    (CVE-2017-5335, CVE-2017-5336, CVE-2017-5337)

    Additional Changes:

    For detailed information on changes in this release, see the Red Hat Enterprise Linux 6.9 Release Notes     and Red Hat Enterprise Linux 6.9 Technical Notes linked from the References section.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

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