Mandriva Linux Security Advisory 2012-159 - Stack-based buffer overflow in the cbtls_verify function in FreeRADIUS 2.1.10 through 2.1.12, when using TLS-based EAP methods, allows remote attackers to cause a denial of service and possibly execute arbitrary code via a long not after timestamp in a client certificate. The updated packages have been patched to correct this issue.
