The Kerberos credential renewal feature in Sun Solaris 8, 9, and 10, and OpenSolaris build snv01 through snv104, allows local users to cause a denial of service (authentication failure) via unspecified vectors related to incorrect cache file permissions, and lack of credential storage by the storecred function in pamkrb5.

Solaris 9, with Solaris Auditing enabled and certain patches for sshd installed, can generate audit records with an audit-ID of 0 even when the user logging into ssh is not root, which makes it easier for attackers to avoid detection and can make it more difficult to conduct forensics activities.
