CVE-2013-0169

A timing side channel attack has been found in CBC padding allowing an attacker to recover pieces of plaintext via statistical analysis of crafted packages, known as the Lucky Thirteen issue.

CVE-2013-1621

An array index error might allow remote attackers to cause a denial of service via vectors involving a crafted padding-length value during validation of CBC padding in a TLS session.

CVE-2013-1622

Malformed CBC data in a TLS session could allow remote attackers to conduct distinguishing attacks via statistical analysis of timing side-channel data for crafted packets.

For the stable distribution (squeeze), these problems have been fixed in version 0.12.1-1squeeze1.

For the testing distribution (wheezy), and the unstable distribution (sid), these problems have been fixed in version 1.1.4-2.

We recommend that you upgrade your polarssl packages.");
