Apple · Macos X · CVE-2006-4397
**Name of the Vulnerable Software and Affected Versions**
Apple Mac OS X versions 10.4 through 10.4.7
**Description**
The issue is related to an unchecked error condition in the LoginWindow of Apple Mac OS X. This condition prevents Kerberos tickets from being destroyed if a user fails to log on to a network account from the login window. As a result, later users might be able to gain access to the original user's Kerberos tickets.
**Recommendations**
For Apple Mac OS X versions 10.4 through 10.4.7, consider updating to a version outside of this range to mitigate the risk of unauthorized access to Kerberos tickets. As a temporary workaround, restrict access to sensitive network resources to minimize the risk of exploitation.
