Debian: Security update for PolarSSL

Multiple vulnerabilities have been found in PolarSSL. 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. 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 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.

Updated packages are available from security.debian.org.

Debian Bug     : 699887

Multiple vulnerabilities have been found in OpenSSL. The Common
Vulnerabilities and Exposures project identifies the following issues:

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.
