The key_certify function in usr.bin/ssh/key.c in OpenSSH 5.6 and 5.7, when generating legacy certificates using the -t command-line option in ssh-keygen, does not initialize the nonce field, which might allow remote attackers to obtain sensitive stack memory contents or make it easier to conduct hash collision attacks. La función key_certify en usr.bin/ssh/key.c en OpenSSH v5.6 y v5.7 al generar los certificados de herencia con la opción de línea de comandos -t en ssh-keygen, no se inicializa el campo nonce, que podría permitir a atacantes remotos obtener contenido sensible de la pila de memoria o que sea más fácil de llevar a cabo ataques de colisión hash. • http://h20000.www2.hp.com/bizsupport/TechSupport/Document.jsp?objectID=c02794777 http://kb.juniper.net/InfoCenter/index?page=content&id=JSA10673 http://secunia.com/advisories/43181 http://secunia.com/advisories/44269 http://www.openssh.com/txt/legacy-cert.adv http://www.openwall.com/lists/oss-security/2011/02/04/2 http://www.securityfocus.com/bid/46155 http://www.securitytracker.com/id?1025028 http://www.vupen.com/english/advisories/2011/0284 https://exchange.xforce.ibmcloud. • CWE-264: Permissions, Privileges, and Access Controls •

OpenSSH 5.6 and earlier, when J-PAKE is enabled, does not properly validate the public parameters in the J-PAKE protocol, which allows remote attackers to bypass the need for knowledge of the shared secret, and successfully authenticate, by sending crafted values in each round of the protocol, a related issue to CVE-2010-4252. OpenSSH v5.6 y versiones anteriores, si J-PAKE está activo, no valida apropiadamente los parámetros públicos en el protocolo J-PAKE, lo que permite a atacantes remotos evitar la necesidad de conocer el secreto compartido, y autenticarse con éxito, enviando valores modificados en cada turno del protocolo.

A certain Debian patch for OpenSSH before 4.3p2-9etch3 on etch; before 4.6p1-1 on sid and lenny; and on other distributions such as SUSE uses functions that are not async-signal-safe in the signal handler for login timeouts, which allows remote attackers to cause a denial of service (connection slot exhaustion) via multiple login attempts. NOTE: this issue exists because of an incorrect fix for CVE-2006-5051. Cierto parche de Debian para OpenSSH en versiones anteriores a 4.3p2-9etch3 en etch, y versiones anteriores a 4.6p1-1 en sid y lenny, que utiliza funciones que no son señales asíncronas seguras (async-signal-safe) en el gestor de señales para los tiempos de autentificado, el cual permite a los atacantes remotos causar una denegación de servicio (agotamiento de la ranura de conexión) a través de múltiples intentos de autenticación.
