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. Relacionado con CVE-2010-4252. • http://kb.juniper.net/InfoCenter/index?page=content&id=JSA10673 http://seb.dbzteam.org/crypto/jpake-session-key-retrieval.pdf http://www.openbsd.org/cgi-bin/cvsweb/src/usr.bin/ssh/jpake.c#rev1.5 http://www.openbsd.org/cgi-bin/cvsweb/src/usr.bin/ssh/jpake.c.diff?r1=1.4%3Br2=1.5%3Bf=h https://bugzilla.redhat.com/show_bug.cgi?id=659297 https://github.com/seb-m/jpake https://oval.cisecurity.org/repository/search/definition/oval%3Aorg.mitre.oval%3Adef%3A12338 • CWE-287: Improper Authentication •

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.

Certain Red Hat Enterprise Linux (RHEL) 4 and 5 packages for OpenSSH, as signed in August 2008 using a legitimate Red Hat GPG key, contain an externally introduced modification (Trojan Horse) that allows the package authors to have an unknown impact. NOTE: since the malicious packages were not distributed from any official Red Hat sources, the scope of this issue is restricted to users who may have obtained these packages through unofficial distribution points. As of 20080827, no unofficial distributions of this software are known.

OpenSSH before 5.1 sets the SO_REUSEADDR socket option when the X11UseLocalhost configuration setting is disabled, which allows local users on some platforms to hijack the X11 forwarding port via a bind to a single IP address, as demonstrated on the HP-UX platform. OpenSSH anterior a 5.1 activa la opción del socket SO_REUSEADDR cuando la configuración X11UseLocalhost está desactivada, lo que permite a usuarios locales en determinadas plataformas, secuestrar el puerto de reenvío X11 a través de una única dirección IP como se ha demostrado sobre la plataforma HP-UX. • http://openssh.com/security.html http://secunia.com/advisories/31179 http://www.openssh.com/txt/release-5.1 http://www.securityfocus.com/bid/30339 http://www.securitytracker.com/id?1020537 http://www.vupen.com/english/advisories/2008/2148 https://exchange.xforce.ibmcloud.com/vulnerabilities/43940 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
