ext/openssl/ossl_ocsp.c in Ruby 1.8 and 1.9 does not properly check the return value from the OCSP_basic_verify function, which might allow remote attackers to successfully present an invalid X.509 certificate, possibly involving a revoked certificate. ext/openssl/ossl_ocsp.c en Ruby v1.8 y v1.9 no comprueba adecuadamente el valor de retorno de la funcion OCSP_basic_verify, lo cual permitiria a atacantes remotos tener exito en la presentacion de un certificado X.509 invalido, posiblemente utilizando un certificado revocado. • http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=513528 http://redmine.ruby-lang.org/issues/show/1091 http://secunia.com/advisories/33750 http://secunia.com/advisories/35699 http://secunia.com/advisories/35937 http://www.mandriva.com/security/advisories?name=MDVSA-2009:193 http://www.redhat.com/support/errata/RHSA-2009-1140.html http://www.securityfocus.com/bid/33769 http://www.securitytracker.com/id?1022505 http://www.ubuntu.com/usn/USN-805-1 https://exchange.xfor • CWE-287: Improper Authentication •

The REXML module in Ruby 1.8.6 through 1.8.6-p287, 1.8.7 through 1.8.7-p72, and 1.9 allows context-dependent attackers to cause a denial of service (CPU consumption) via an XML document with recursively nested entities, aka an "XML entity explosion." El módulo REXML en Ruby 1.8.6 hasta la versión 1.8.6-p287, 1.8.7 hasta 1.8.7-p72, y 1.9 permite que atacantes, dependiendo del contexto, provocar una denegación de servicio (agotamiento CPU) a través de un documento XML con entidades anidadas recursivamente, también conocido como "Explosión de entidades XML". • https://www.exploit-db.com/exploits/32292 http://groups.google.com/group/comp.lang.ruby/browse_thread/thread/19f69e8a081fc0d1/e138e014b74352ca http://lists.apple.com/archives/security-announce/2009/May/msg00002.html http://secunia.com/advisories/31602 http://secunia.com/advisories/32165 http://secunia.com/advisories/32219 http://secunia.com/advisories/32255 http://secunia.com/advisories/32256 http://secunia.com/advisories/32371 http://secunia.com/advisories/33178 http://secunia.com/ • CWE-20: Improper Input Validation •

The regular expression engine (regex.c) in Ruby 1.8.5 and earlier, 1.8.6 through 1.8.6-p286, 1.8.7 through 1.8.7-p71, and 1.9 through r18423 allows remote attackers to cause a denial of service (infinite loop and crash) via multiple long requests to a Ruby socket, related to memory allocation failure, and as demonstrated against Webrick. El motor de expresiones regulares (regex.c) en Ruby 1.8.5 y anteriores, 1.8.6 a través de p286-1.8.6, 1.8.7 a través de 1.8.7-p71, y 1.9 a través de r18423 permite a atacantes remotos provocar una denegación de servicio (bucle infinito y caida) a través de múltiples peticiones largas a un socket de Ruby. Esta denegación de servicio esta relacionada con un fallo en la asignación de memoria, como se ha demostrado contra Webrick. • https://www.exploit-db.com/exploits/6239 http://lists.apple.com/archives/security-announce/2009/May/msg00002.html http://secunia.com/advisories/31430 http://secunia.com/advisories/32165 http://secunia.com/advisories/32219 http://secunia.com/advisories/32371 http://secunia.com/advisories/32372 http://secunia.com/advisories/33185 http://secunia.com/advisories/33398 http://secunia.com/advisories/35074 http://securityreason.com/securityalert/4158 http://support.apple.com/kb/HT3549 • CWE-399: Resource Management Errors •

Ruby 1.8.5 and earlier, 1.8.6 through 1.8.6-p286, 1.8.7 through 1.8.7-p71, and 1.9 through r18423 does not properly restrict access to critical variables and methods at various safe levels, which allows context-dependent attackers to bypass intended access restrictions via (1) untrace_var, (2) $PROGRAM_NAME, and (3) syslog at safe level 4, and (4) insecure methods at safe levels 1 through 3. Ruby versiones 1.8.5 y anteriores, versiones 1.8.6 hasta 1.8.6-p286, versiones 1.8.7 hasta 1.8.7-p71, y versiones 1.9 hasta r18423, no restringe apropiadamente el acceso a variables y métodos críticos en varios niveles seguros, lo que permite a los atacantes dependiendo del contexto omitir las restricciones de acceso previstas por medio de (1) untrace_var, (2) $PROGRAM_NAME, y (3) syslog en nivel seguro 4 y (4) métodos no confiables en los niveles seguros 1 a 3. • https://www.exploit-db.com/exploits/32224 https://www.exploit-db.com/exploits/32223 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=494401 http://lists.apple.com/archives/security-announce/2009/May/msg00002.html http://secunia.com/advisories/31430 http://secunia.com/advisories/31697 http://secunia.com/advisories/32165 http://secunia.com/advisories/32219 http://secunia.com/advisories/32255 http://secunia.com/advisories/32256 http://secunia.com/advisories/32371 http:// • CWE-264: Permissions, Privileges, and Access Controls •
