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.

Security readout for executives and security teams

This issue affects OpenSSH in Fedora and Red Hat Enterprise Linux 7 Kerberos environments. An already authenticated remote user listed in another user’s .k5users file may be able to SSH as that user, bypassing intended requirements such as forcing local login. Exposure appears limited to Fedora or Red Hat Enterprise Linux 7 systems running OpenSSH in a Kerberos environment using .k5users delegation. General OpenSSH deployments without Kerberos or without relevant .k5users entries are not identified as affected in the provided sources. Treat this as a targeted access-control issue rather than an internet-wide emergency. Prioritize review on Kerberos-enabled Linux servers that protect privileged, service, or administrator accounts with local-login requirements. Mitigation focus: Apply vendor updates referenced by Red Hat advisory RHSA-2015:0425 where applicable.; Review Fedora and RHEL 7 OpenSSH Kerberos configurations against vendor guidance.; Audit .k5users files for unintended user delegation relationships..
