"Multiple vulnerabilities have been found in PolarSSL. 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.");
