OpenSSH 7.7 through 7.9 and 8.x before 8.1, when compiled with an experimental key type, has a pre-authentication integer overflow if a client or server is configured to use a crafted XMSS key. This leads to memory corruption and local code execution because of an error in the XMSS key parsing algorithm. NOTE: the XMSS implementation is considered experimental in all released OpenSSH versions, and there is no supported way to enable it when building portable OpenSSH. OpenSSH 7.7 a 7.9 y 8.x anterior de la versión 8.1, cuando se compila con un tipo de clave experimental, tiene un desbordamiento de entero de identificación previa si un cliente o servidor está configurado para usar una clave XMSS especialmente diseñada. Esto conduce a la corrupción de la memoria y la ejecución del código local debido a un error en el algoritmo de análisis de claves XMSS. • https://0day.life/exploits/0day-1009.html https://bugzilla.suse.com/show_bug.cgi?id=1153537 https://cert-portal.siemens.com/productcert/pdf/ssa-412672.pdf https://cvsweb.openbsd.org/cgi-bin/cvsweb/src/usr.bin/ssh/sshkey-xmss.c https://cvsweb.openbsd.org/cgi-bin/cvsweb/src/usr.bin/ssh/sshkey-xmss.c.diff?r1=1.5&r2=1.6&f=h https://security.gentoo.org/glsa/201911-01 https://security.netapp.com/advisory/ntap-20191024-0003 https://ssd-disclosure.com/archives/4033&#x • CWE-190: Integer Overflow or Wraparound •

OpenSSH-portable (OpenSSH) 3.6.1p1 and earlier with PAM support enabled immediately sends an error message when a user does not exist, which allows remote attackers to determine valid usernames via a timing attack. OpenSSH-portable (OpenSSH) 3.6.1p1 y anteriores con soporte PAM activado envía inmediatamente un mensaje de error cuando un usuario no existe, lo que permite a atacantes remotos determinar nombres de usuario válidos mediante un ataque de temporización. • https://www.exploit-db.com/exploits/26 https://www.exploit-db.com/exploits/25 https://www.exploit-db.com/exploits/3303 http://lab.mediaservice.net/advisory/2003-01-openssh.txt http://lists.grok.org.uk/pipermail/full-disclosure/2003-April/004815.html http://marc.info/?l=bugtraq&m=105172058404810&w=2 http://marc.info/?l=bugtraq&m=106018677302607&w=2 http://www.redhat.com/support/errata/RHSA-2003-222.html http://www.redhat.com/support/errata/RHSA-2003-224.html • CWE-203: Observable Discrepancy •
