https://notcve.org/view.php?id=CVE-2014-9278
The OpenSSH server, as used in Fedora and Red Hat Enterprise Linux 7 and when running in a Kerberos environment, allows remote authenticated users to log in as another user when they are listed in the .k5users file of that user, which might bypass intended authentication requirements that would force a local login. El servidor OpenSSH, utilizado en Fedora y Red Hat Enterprise Linux 7 y cuando funciona en un entorno Kerberos, permite a usuarios remotos autenticados iniciar sesión como otro usuario cuando están listados en el fichero .k5users de ese usuario, lo que podría evadir los requisitos de autenticación que forzaría un inicio de sesión local. It was found that when OpenSSH was used in a Kerberos environment, remote authenticated users were allowed to log in as a different user if they were listed in the ~/.k5users file of that user, potentially bypassing intended authentication restrictions. • http://rhn.redhat.com/errata/RHSA-2015-0425.html http://thread.gmane.org/gmane.comp.encryption.kerberos.general/15855 http://www.openwall.com/lists/oss-security/2014/12/02/3 http://www.openwall.com/lists/oss-security/2014/12/04/17 http://www.securityfocus.com/bid/71420 https://bugzilla.mindrot.org/show_bug.cgi?id=1867 https://bugzilla.redhat.com/show_bug.cgi?id=1169843 https://exchange.xforce.ibmcloud.com/vulnerabilities/99090 https://access.redhat.com/security/cve/CVE • CWE-287: Improper Authentication •
