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 (3.6.8). (BZ#1689967)

Security Fix(es) :

* gnutls: use-after-free/double-free in certificate verification
(CVE-2019-3829)

* gnutls: invalid pointer access upon receiving async handshake
messages (CVE-2019-3836)

For more details about the security issue(s), including the impact, a
CVSS score, acknowledgments, and other related information, refer to
the CVE page(s) listed in the References section.

Additional Changes :

For detailed information on changes in this release, see the Red Hat
Enterprise Linux 8.1 Release Notes linked from the References section."

issue only affected Ubuntu 16.04 LTS and Ubuntu 18.04 LTS.

Tavis Ormandy discovered that GnuTLS incorrectly handled memory when
verifying certain X.509 certificates. A remote attacker could use this
issue to cause GnuTLS to crash, resulting in a denial of service, or
possibly execute arbitrary code. This issue only affected Ubuntu 18.04
LTS, Ubuntu 18.10, and Ubuntu 19.04. (CVE-2019-3829)

It was discovered that GnuTLS incorrectly handled certain
post-handshake messages. A remote attacker could use this issue to
cause GnuTLS to crash, resulting in a denial of service, or possibly
execute arbitrary code. This issue only affected Ubuntu 18.10 and
Ubuntu 19.04. (CVE-2019-3836).
