Debian Security Advisory DSA 2782-1 (polarssl - Several Vulnerabilities) Network Vulnerability

Summary

Multiple security issues have been discovered in PolarSSL, a lightweight crypto and SSL/TLS library: CVE-2013-4623 Jack Lloyd discovered a denial of service vulnerability in the parsing of PEM-encoded certificates. CVE-2013-5914 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.

Solution

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.
