Descriptions

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 (server crash) and possibly execute arbitrary code via a long "not after" timestamp in a client certificate.
