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.
