Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.
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).
