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 Red Hat modification to the ChrootDirectory feature in OpenSSH 4.8, as used in sshd in OpenSSH 4.3 in Red Hat Enterprise Linux (RHEL) 5.4 and Fedora 11, allows local users to gain privileges via hard links to setuid programs that use configuration files within the chroot directory, related to requirements for directory ownership. Ciertas modificaciones Ret Hat en ChrootDirectory feature en OpenSSH v4.8, como el usado en sshd en OpenSSH v4.3 en Red Hat Enterprise Linux (RHEL) v5.4 y Fedora v11, permite a usuarios locales obtener privilegios a través de enlaces fuertes en programas setuid que usa una configuración de ficheros con el chroot directory, relacionado con requerimientos para el propietario. • http://lists.fedoraproject.org/pipermail/package-announce/2010-March/038214.html http://lists.vmware.com/pipermail/security-announce/2010/000082.html http://osvdb.org/58495 http://secunia.com/advisories/38794 http://secunia.com/advisories/38834 http://secunia.com/advisories/39182 http://www.securityfocus.com/bid/36552 http://www.vupen.com/english/advisories/2010/0528 https://bugzilla.redhat.com/show_bug.cgi?id=522141 https://oval.cisecurity.org/repository/search/definition/oval%3Aorg&# • CWE-16: Configuration •

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. NOTA: esto existe por una incorrecta solución de CVE-2006-5051. • http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=498678 http://lists.opensuse.org/opensuse-security-announce/2008-10/msg00004.html http://secunia.com/advisories/31885 http://secunia.com/advisories/32080 http://secunia.com/advisories/32181 http://www.debian.org/security/2008/dsa-1638 http://www.openwall.com/lists/oss-security/2024/07/01/3 http://www.securitytracker.com/id?1020891 http://www.ubuntu.com/usn/usn-649-1 https://exchange.xforce.ibmcloud.com/vulnerabilities/4520 • CWE-264: Permissions, Privileges, and Access Controls •

https://notcve.org/view.php?id=CVE-2008-3259
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 •

OpenSSH 4.3p2, and probably other versions, allows local users to hijack forwarded X connections by causing ssh to set DISPLAY to :10, even when another process is listening on the associated port, as demonstrated by opening TCP port 6010 (IPv4) and sniffing a cookie sent by Emacs. OpenSSH 4.3p2 y probablemente otras versiones, permite a usuarios locales secuestrar conexiones X enviadas provocando que ssh ponga DISPLAY a :10, incluso cuando otro proceso está escuchando en el puerto asociado, como se demostró abriendo el puerto TCp 6010 (IPv4) y escaneando una cookie enviada por Emacs. • ftp://ftp.netbsd.org/pub/NetBSD/security/advisories/NetBSD-SA2008-005.txt.asc http://aix.software.ibm.com/aix/efixes/security/ssh_advisory.asc http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=463011 http://h20000.www2.hp.com/bizsupport/TechSupport/Document.jsp?objectID=c01462841 http://lists.apple.com/archives/security-announce//2008/Sep/msg00005.html http://lists.opensuse.org/opensuse-security-announce/2008-04/msg00007.html http://secunia.com/advisories/29522 http://secunia.com/adviso • CWE-264: Permissions, Privileges, and Access Controls •
