Multiple security issues have been discovered in PolarSSL, a lightweight crypto and SSL/TLS library:

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

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.
