https://notcve.org/view.php?id=CVE-2008-5161
Error handling in the SSH protocol in (1) SSH Tectia Client and Server and Connector 4.0 through 4.4.11, 5.0 through 5.2.4, and 5.3 through 5.3.8; Client and Server and ConnectSecure 6.0 through 6.0.4; Server for Linux on IBM System z 6.0.4; Server for IBM z/OS 5.5.1 and earlier, 6.0.0, and 6.0.1; and Client 4.0-J through 4.3.3-J and 4.0-K through 4.3.10-K; and (2) OpenSSH 4.7p1 and possibly other versions, when using a block cipher algorithm in Cipher Block Chaining (CBC) mode, makes it easier for remote attackers to recover certain plaintext data from an arbitrary block of ciphertext in an SSH session via unknown vectors.

CVE-2008-4109
https://notcve.org/view.php?id=CVE-2008-4109
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 •
CVE-2008-3259
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 •

https://notcve.org/view.php?id=CVE-2008-3234
sshd in OpenSSH 4 on Debian GNU/Linux, and the 20070303 OpenSSH snapshot, allows remote authenticated users to obtain access to arbitrary SELinux roles by appending a :/ (colon slash) sequence, followed by the role name, to the username. sshd en OpenSSH 4 sobre Debian GNU/Linux, y el OpenSSH Snapshot 20070303, permiten que usuarios remotos autenticados obtener acceso a roles de usuario SELinux arbitrarios añadiendo al nombre de usuario una secuencia :/ (dos puntos - barra), seguido por el nombre del rol de usuario que se desee. • https://www.exploit-db.com/exploits/6094 http://www.securityfocus.com/bid/30276 https://exchange.xforce.ibmcloud.com/vulnerabilities/44037 • CWE-264: Permissions, Privileges, and Access Controls •
