Problem description

Multiple vulnerabilities has been found and corrected in gnutls:

A flaw was found in the way the TLS/SSL (Transport Layer
Security/Secure Sockets Layer) protocols handled session
renegotiation. A man-in-the-middle attacker could use this flaw
to prefix arbitrary plain text to a client's session (for example,
an HTTPS connection to a website). This could force the server to
process an attacker's request as if authenticated using the victim's
credentials. This update addresses this flaw by implementing the
TLS Renegotiation Indication Extension, as defined in RFC 5746
(CVE-2009-3555).

The TLS implementation in GnuTLS before 2.12.23, 3.0.x before 3.0.28,
and 3.1.x before 3.1.7 does not properly consider timing side-channel
attacks on a noncompliant MAC check operation during the processing
of malformed CBC padding, which allows remote attackers to conduct
distinguishing attacks and plaintext-recovery attacks via statistical
analysis of timing data for crafted packets, a related issue to
CVE-2013-0169 (CVE-2013-1619).

The updated packages have been patched to correct these issues.
