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. Desbordamiento de búfer basado en pila en la función cbtls_verify en FreeRADIUS v2.1.10 hasta la v2.1.12, cuando se usan los métodos TLS-based EAP, permite a atacantes remotos provocar una denegación de servicio (caída del servidor) y posiblemente ejecutar código a través de un sellado de tiempo "not after" largo, en un certificado de un cliente. • http://archives.neohapsis.com/archives/bugtraq/2012-09/0043.html http://freeradius.org/security.html http://lists.apple.com/archives/security-announce/2013/Oct/msg00006.html http://lists.fedoraproject.org/pipermail/package-announce/2012-October/090171.html http://lists.opensuse.org/opensuse-security-announce/2012-09/msg00023.html http://osvdb.org/85325 http://rhn.redhat.com/errata/RHSA-2012-1326.html http://rhn.redhat.com/errata/RHSA-2012-1327.html http://secunia.com/advisories/50484&# • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-121: Stack-based Buffer Overflow •
