DESCRIPTION:
A vulnerability has been reported in Microsoft Windows, which can be
exploited by malicious, local users to gain escalated privileges.
The vulnerability is caused due to the Kerberos implementation
supporting a weak hashing mechanism (e.g. CRC32). This can be
exploited to forge a service ticket and obtain a token with elevated
privileges.
SOLUTION:
Apply patches.
