 Mandriva Linux Security Advisory                         MDVSA-2013:019
 http://www.mandriva.com/en/support/security/
 _______________________________________________________________________

 Package : gnutls
 Date    : March 7, 2013
 Affected: Enterprise Server 5.0
 _______________________________________________________________________

 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.
