CVE-2014-9278
First published: Tue Dec 02 2014(Updated: )
IssueDescription: In a Kerberos environment, OpenSSH allows remote, authenticated users to log in as another user if they are listed in a ~/.k5users file of that other user. This unexpectedly alters the system security policy, as expressed through the ~/.k5users file, because previously, users would have to log in locally, potentially requiring different forms of authentication, before they could use the ksu command to switch users.
