| 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 (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)
