|MS10-013||Vulnerability in Microsoft DirectShow Could Allow Remote Code Execution (977935)||Microsoft Windows||Critical||10-02-2010|
Brief overview of the risk:
This security update resolves a privately reported vulnerability in Microsoft Windows. The vulnerability could allow denial of service if a specially crafted ticket renewal request is sent to the Windows Kerberos domain from an authenticated user on a trusted non-Windows Kerberos realm. The denial of service could persist until the domain controller is restarted.
Detailed Information on the risk:
A denial of service vulnerability exists in implementations of Kerberos. The vulnerability is due to improper handling of Ticket-Granting-Ticket renewal requests by a client on a remote, non-Windows realm in a mixed-mode Kerberos implementation. An attacker who successfully exploited this vulnerability could cause the affected Windows domain controller to stop responding.
