Multiple stack-based buffer overflows in libopensc in OpenSC 0.11.13 and earlier allow physically proximate attackers to execute arbitrary code via a long serial-number field on a smart card, related to (1) card-acos5.c, (2) card-atrust-acos.c, and (3) card-starcos.c. Múltiples desbordamientos de búfer basado en pila en libopensc en OpenSC v0.11.13 y anteriores permite a atacantes físicamente próximos ejecutar código arbitrario a través de un campo largo serial-number de una tarjeta inteligente, relacionado con (1) card-acos5.c, (2) card-atrust-acos.c, y (3) card-starcos.c. • http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=607427 http://labs.mwrinfosecurity.com/files/Advisories/mwri_opensc-get-serial-buffer-overflow_2010-12-13.pdf http://lists.fedoraproject.org/pipermail/package-announce/2011-January/052777.html http://lists.fedoraproject.org/pipermail/package-announce/2011-January/052796.html http://lists.opensuse.org/opensuse-security-announce/2011-01/msg00006.html http://openwall.com/lists/oss-security/2010/12/21/2 http://openwall.com/lists/oss-security/2010/12&# • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •

OpenSC before 0.11.7 allows physically proximate attackers to bypass intended PIN requirements and read private data objects via a (1) low level APDU command or (2) debugging tool, as demonstrated by reading the 4601 or 4701 file with the opensc-explorer or opensc-tool program. Vulnerabilidad en OpenSC en versiones anteriores a v0.11.7 que permite a atacantes próximos físicamente evitar los requisitos de autenticación/validación de PIN a través de (1) el comando APDU de bajo nivel o (2) una herramienta de depuración de errores, como se ha demostrado leyendo el fichero 4601 o 4701 con el programa opensc-explorer o opensc-tool. • https://www.exploit-db.com/exploits/32820 http://lists.opensuse.org/opensuse-security-announce/2009-05/msg00000.html http://openwall.com/lists/oss-security/2009/02/26/1 http://secunia.com/advisories/34052 http://secunia.com/advisories/34120 http://secunia.com/advisories/34362 http://secunia.com/advisories/34377 http://secunia.com/advisories/35065 http://secunia.com/advisories/36074 http://security.gentoo.org/glsa/glsa-200908-01.xml http://www.debian.org/security/2009 • CWE-310: Cryptographic Issues •

pkcs15-tool in OpenSC before 0.11.6 does not apply security updates to a smart card unless the card's label matches the "OpenSC" string, which might allow physically proximate attackers to exploit vulnerabilities that the card owner expected were patched, as demonstrated by exploitation of CVE-2008-2235. pkcs15-tool en OpenSC antes de 0.11.6 no aplica las actualizaciones de seguridad a una tarjeta inteligente a menos que la etiqueta de la tarjeta corresponda con la cadena "OpenSC", lo que podría permitir a atacantes físicamente próximos explotar vulnerabilidades que el propietario de la tarjeta creía que estaban parcheadas, como se demostró con la explotación de CVE-2008-2235. • http://lists.opensuse.org/opensuse-security-announce/2008-09/msg00005.html http://secunia.com/advisories/32099 http://secunia.com/advisories/34362 http://www.opensc-project.org/pipermail/opensc-announce/2008-August/000021.html http://www.openwall.com/lists/oss-security/2008/09/09/14 https://exchange.xforce.ibmcloud.com/vulnerabilities/45045 https://www.redhat.com/archives/fedora-package-announce/2009-March/msg00686.html • CWE-264: Permissions, Privileges, and Access Controls •

OpenSC before 0.11.5 uses weak permissions (ADMIN file control information of 00) for the 5015 directory on smart cards and USB crypto tokens running Siemens CardOS M4, which allows physically proximate attackers to change the PIN. OpenSC anterior a 0.11.5 usa permisos débiles (archivo de control de información ADMIN de 00) para el directorio 5015 en smart cards y crypto tokens USB ejecutándose Siemens CardOS M4, que permite a atacantes próximos físicamente cambiar el PIN. • http://lists.opensuse.org/opensuse-security-announce/2008-09/msg00005.html http://lists.opensuse.org/opensuse-security-announce/2009-02/msg00002.html http://secunia.com/advisories/31330 http://secunia.com/advisories/31360 http://secunia.com/advisories/32099 http://secunia.com/advisories/33115 http://secunia.com/advisories/34362 http://security.gentoo.org/glsa/glsa-200812-09.xml http://www.mandriva.com/security/advisories?name=MDVSA-2008:183 http://www.opensc-project.org/pipermail/opens • CWE-310: Cryptographic Issues •
