The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2017:2292 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 (3.3.26). (BZ#1378373)

    Security Fix(es):

    * A double-free flaw was found in the way GnuTLS parsed certain X.509 certificates with Proxy Certificate     Information extension. An attacker could create a specially-crafted certificate which, when processed by     an application compiled against GnuTLS, could cause that application to crash. (CVE-2017-5334)

    * 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, CVE-2017-7869)

    * A null pointer dereference flaw was found in the way GnuTLS processed ClientHello messages with     status_request extension. A remote attacker could use this flaw to cause an application compiled with     GnuTLS to crash. (CVE-2017-7507)

    * A flaw was found in the way GnuTLS validated certificates using OCSP responses. This could falsely     report a certificate as valid under certain circumstances. (CVE-2016-7444)

    The CVE-2017-7507 issue was discovered by Hubert Kario (Red Hat QE BaseOS Security team).

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.
