Description: | 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)
