CVSS: 6.8EPSS: 6%CPEs: 3EXPL: 0CVE-2012-3547 – freeradius: stack-based buffer overflow via long expiration date fields in client X509 certificates
https://notcve.org/view.php?id=CVE-2012-3547
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 •

https://notcve.org/view.php?id=CVE-2011-2701
The ocsp_check function in rlm_eap_tls.c in FreeRADIUS 2.1.11, when OCSP is enabled, does not properly parse replies from OCSP responders, which allows remote attackers to bypass authentication by using the EAP-TLS protocol with a revoked X.509 client certificate. La función ocsp_check de rlm_eap_tls.c de FreeRADIUS 2.1.11, si OCSP está habilitado, no analiza correctamente la sintaxis ("parse") de las respuestas de los agentes transmisores OCSP, lo que permite a atacantes remotos evitar la autenticación usando el protocolo EAP-TLS con un certificado cliente X.509 revocado. • http://secunia.com/advisories/45425 http://securityreason.com/securityalert/8325 http://securitytracker.com/id?1025833 http://www.openwall.com/lists/oss-security/2011/07/15/6 http://www.openwall.com/lists/oss-security/2011/07/18/2 http://www.openwall.com/lists/oss-security/2011/07/20/9 http://www.securityfocus.com/archive/1/518974/100/0/threaded http://www.securityfocus.com/bid/48880 https://bugzilla.redhat.com/show_bug.cgi?id=724815 https://exchange.xforce.ib • CWE-287: Improper Authentication •
