The remote Red Hat host is missing one or more security updates.
Updated gnutls packages that fix one security issue are now available
for Red Hat Enterprise Linux 5 and 6.
The Red Hat Security Response Team has rated this update as having
moderate security impact. A Common Vulnerability Scoring System (CVSS)
base score, which gives a detailed severity rating, is available from
the CVE link in the References section.
The GnuTLS library provides support for cryptographic algorithms and
for protocols such as Transport Layer Security (TLS).
It was discovered that GnuTLS leaked timing information when
decrypting TLS/SSL protocol encrypted records when CBC-mode cipher
suites were used. A remote attacker could possibly use this flaw to
retrieve plain text from the encrypted packets by using a TLS/SSL
server as a padding oracle. (CVE-2013-1619)
Users of GnuTLS are advised to upgrade to these updated packages,
which contain a backported patch to correct this issue. For the update
to take effect, all applications linked to the GnuTLS library must be
restarted, or the system rebooted.
