CVE-2007-4752 – openssh falls back to the trusted x11 cookie if generation of an untrusted cookie fails
https://notcve.org/view.php?id=CVE-2007-4752
ssh in OpenSSH before 4.7 does not properly handle when an untrusted cookie cannot be created and uses a trusted X11 cookie instead, which allows attackers to violate intended policy and gain privileges by causing an X client to be treated as trusted. ssh en OpenSSH anterior a 4.7 no maneja adecuadamente cuando una cookie no confiable no puede ser creada y utiliza una cookie X11 confiable en su lugar, lo cual permite a los atacantes violar políticas establecidas y obtener privilegios provocando que un cliente X sea tratado como confiable. • http://bugs.gentoo.org/show_bug.cgi?id=191321 http://docs.info.apple.com/article.html?artnum=307562 http://h20000.www2.hp.com/bizsupport/TechSupport/Document.jsp?objectID=c01271085 http://lists.apple.com/archives/security-announce/2008/Mar/msg00001.html http://lists.opensuse.org/opensuse-security-announce/2007-10/msg00008.html http://secunia.com/advisories/27399 http://secunia.com/advisories/29420 http://secunia.com/advisories/30249 http://secunia.com/advisories/31575 http://secunia. • CWE-20: Improper Input Validation •
CVE-2007-2243 – OpenSSH s/key Weakness
https://notcve.org/view.php?id=CVE-2007-2243
OpenSSH 4.6 and earlier, when ChallengeResponseAuthentication is enabled, allows remote attackers to determine the existence of user accounts by attempting to authenticate via S/KEY, which displays a different response if the user account exists, a similar issue to CVE-2001-1483. OpenSSH 4.6 y anteriores, cuando ChallengeResponseAuthentication está habilitado, permite a atacantes remotos determinar la existencia de cuentas de usuario intentando autenticarse mediante S/KEY, lo cual muestra una respuesta diferente si la cuenta de usuario existe, un problema similar a CVE-2001-1483. OpenSSH, when configured to use S/KEY authentication, is prone to a remoteinformation disclosure weakness. • http://lists.grok.org.uk/pipermail/full-disclosure/2007-April/053906.html http://lists.grok.org.uk/pipermail/full-disclosure/2007-April/053951.html http://securityreason.com/securityalert/2631 http://www.osvdb.org/34600 http://www.securityfocus.com/bid/23601 https://exchange.xforce.ibmcloud.com/vulnerabilities/33794 https://security.netapp.com/advisory/ntap-20191107-0003 • CWE-287: Improper Authentication •
CVE-2006-5794 – OpenSSH privilege separation flaw
https://notcve.org/view.php?id=CVE-2006-5794
Unspecified vulnerability in the sshd Privilege Separation Monitor in OpenSSH before 4.5 causes weaker verification that authentication has been successful, which might allow attackers to bypass authentication. NOTE: as of 20061108, it is believed that this issue is only exploitable by leveraging vulnerabilities in the unprivileged process, which are not known to exist. Vulnerabilidad sin especificar en el sshd Privilege Separation Monitor en OpenSSH para versiones anteriores a la 4.5 que provoca una verificación más leve que la autenticación, y que podría permitir a atacantes remotos evitar la autenticación. NOTA: en el 20061108, se cree que es sólo explotada por el impulso de vulnerabilidades en un proceso sin privilegios, hasta ahora desconocidos. • ftp://patches.sgi.com/support/free/security/advisories/20061201-01-P.asc http://rhn.redhat.com/errata/RHSA-2006-0738.html http://secunia.com/advisories/22771 http://secunia.com/advisories/22772 http://secunia.com/advisories/22773 http://secunia.com/advisories/22778 http://secunia.com/advisories/22814 http://secunia.com/advisories/22872 http://secunia.com/advisories/22932 http://secunia.com/advisories/23513 http://secunia.com/advisories/23680 http://secunia.com/advisories •
CVE-2006-5051 – unsafe GSSAPI signal handler
https://notcve.org/view.php?id=CVE-2006-5051
Signal handler race condition in OpenSSH before 4.4 allows remote attackers to cause a denial of service (crash), and possibly execute arbitrary code if GSSAPI authentication is enabled, via unspecified vectors that lead to a double-free. Condición de carrera en el manejador de señal OpenSSH en versiones anteriores a 4.4 permite a atacantes remotos provocar una denegación de servicio (caída) y posiblemente ejecutar código arbitrario si la autenticación GSSAPI está habilitada, a través de vectores no especificados que conducen a una doble liberación. • ftp://ftp.freebsd.org/pub/FreeBSD/CERT/advisories/FreeBSD-SA-06:22.openssh.asc ftp://patches.sgi.com/support/free/security/advisories/20061001-01-P.asc http://docs.info.apple.com/article.html?artnum=305214 http://lists.apple.com/archives/security-announce/2007/Mar/msg00002.html http://lists.freebsd.org/pipermail/freebsd-security/2006-October/004051.html http://marc.info/?l=openssh-unix-dev&m=115939141729160&w=2 http://openssh.org/txt/release-4.4 http://secunia.com/advisories& • CWE-415: Double Free •
