CVE-2012-3547 is a vulnerability of currently unknown severity. 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.. EPSS estimates a 5.65% chance of exploitation in the next 30 days.
