Test ID:1.3.6.1.4.1.25623.1.0.871850
Category:Red Hat Local Security Checks
Title:RedHat Update for gnutls RHSA-2017:2292-01
Summary:The remote host is missing an update for the 'gnutls'; package(s) announced via the referenced advisory.
Description:Summary:
The remote host is missing an update for the 'gnutls'
package(s) announced via the referenced advisory.

Vulnerability Insight:
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). Additional Changes: For detailed information on changes in this release,
see the Red Hat Enterprise Linux 7.4 Release Notes linked from the References
section.

Affected Software/OS:
