CVE-2012-2551

Name of the Vulnerable Software and Affected Versions Microsoft Windows Server 2008 R2 and R2 SP1 Microsoft Windows 7 Gold and SP1

Description A denial of service issue exists due to the improper handling of a specially crafted session by the Microsoft Kerberos implementation. This can cause the system to stop responding and restart when exploited. The issue arises from a crafted session request that leads to a NULL pointer dereference and subsequent system reboot.

Recommendations For Microsoft Windows Server 2008 R2 and R2 SP1, apply the necessary patch to fix the Kerberos implementation. For Microsoft Windows 7 Gold and SP1, apply the necessary patch to fix the Kerberos implementation. As a temporary workaround, consider restricting access to the Kerberos service to minimize the risk of exploitation.
