CVSS: 5.0EPSS: 0%CPEs: 62EXPL: 0CVE-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 •
CVSS: 7.5EPSS: 3%CPEs: 1EXPL: 0CVE-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&#x •

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 •
