CVE-2013-4623: Input Validation
First published: Fri Aug 16 2013(Updated: )
From the PolarSSL Security Advisory 2013-03 advisory: "A bug in the logic of the parsing of PEM encoded certificates in x509parse_crt() can result in an infinite loop, thus hogging processing power." A remote attacker could use this flaw to make a TLS/SSL server using PolarSSL consume an excessive amount of CPU. This issue was corrected in PolarSSL versions 1.1.7 and 1.2.8. (Versions prior to these are affected.)
