CVE-2011-4966 – freeradius: does not respect expired passwords when using the unix module
https://notcve.org/view.php?id=CVE-2011-4966
modules/rlm_unix/rlm_unix.c in FreeRADIUS before 2.2.0, when unix mode is enabled for user authentication, does not properly check the password expiration in /etc/shadow, which allows remote authenticated users to authenticate using an expired password. modules/rlm_unix/rlm_unix.c en FreeRADIUS anterior a v2.2.0, cuando el modo unix está activado para la autenticación de usuarios, no valida adecuadamente la expiración de la contraseña en /etc/shadow, lo que permite a usuarios autenticados remotamente validarse mediante una contraseña caducada. • http://lists.opensuse.org/opensuse-updates/2013-01/msg00029.html http://lists.opensuse.org/opensuse-updates/2013-01/msg00079.html http://rhn.redhat.com/errata/RHBA-2012-0881.html http://rhn.redhat.com/errata/RHSA-2013-0134.html https://github.com/alandekok/freeradius-server/commit/1b1ec5ce75e224bd1755650c18ccdaa6dc53e605 https://access.redhat.com/security/cve/CVE-2011-4966 https://bugzilla.redhat.com/show_bug.cgi?id=879045 • CWE-255: Credentials Management Errors •
CVE-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 •
CVE-2011-2701
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 •
CVE-2010-3697
https://notcve.org/view.php?id=CVE-2010-3697
The wait_for_child_to_die function in main/event.c in FreeRADIUS 2.1.x before 2.1.10, in certain circumstances involving long-term database outages, does not properly handle long queue times for requests, which allows remote attackers to cause a denial of service (daemon crash) by sending many requests. La función wait_for_child_to_die en main/event.c en FreeRADIUS v2.1.x anterior a v2.1.10, en determinadas ocaciones genera cortes en la base de datos al no controlar correctamente los tiempos largos de la cola de peticiones, permitiendo de esta forma a atacantes remotos provocar una denegación de servicio ( caída del servicio) mediante el envío de muchas peticiones. • http://freeradius.org/press/index.html#2.1.10 http://github.com/alandekok/freeradius-server/commit/ff94dd35673bba1476594299d31ce8293b8bd223 http://secunia.com/advisories/41621 http://www.openwall.com/lists/oss-security/2010/10/01/3 http://www.openwall.com/lists/oss-security/2010/10/01/8 https://bugs.freeradius.org/bugzilla/show_bug.cgi?id=35 https://bugzilla.redhat.com/show_bug.cgi?id=639397 • CWE-399: Resource Management Errors •
CVE-2010-3696
https://notcve.org/view.php?id=CVE-2010-3696
The fr_dhcp_decode function in lib/dhcp.c in FreeRADIUS 2.1.9, in certain non-default builds, does not properly handle the DHCP Relay Agent Information option, which allows remote attackers to cause a denial of service (infinite loop and daemon outage) via a packet that has more than one sub-option. NOTE: some of these details are obtained from third party information. La función fr_dhcp_decode en lib/dhcp.c en FreeRADIUS v2.1.9, en determinadas compilaciones (no por defecto), no maneja adecuadamente la opción DHCP Relay Agent Information, lo cual permite a atacantes remotos provocar una denegación de servicio (bucle infinito y corte del servicio) a través de un paquete que tiene más de una sub-opción.
