Jack Lloyd discovered a denial of service vulnerability in the parsing of PEM-encoded certificates.

Paul Brodeur and TrustInSoft discovered a buffer overflow in the ssl_read_record() function, allowing the potential execution of arbitrary code.
CVE-2013-5915
Cyril Arnaud and Pierre-Alain Fouque discovered timing attacks against the RSA implementation.
For the oldstable distribution (squeeze), these problems will be fixed in version 1.2.9-1~deb6u1 soon (due to a technical limitation the updates cannot be released synchronously).
For the stable distribution (wheezy), these problems have been fixed in version 1.2.9-1~deb7u1.
For the unstable distribution (sid), these problems have been fixed in version 1.3.1-1.
We recommend that you upgrade your polarssl packages.");
