Title: Microsoft Windows Kernel Unspecified Remote Desktop Protocol Denial Of Service Vulnerability
Severity: HIGH
Description:
A remote denial of service vulnerability has been reported in the kernel for Microsoft Windows. The vendor has confirmed that this vulnerability permits remote attackers to crash affected computers. This issue is due to a failure of the application to properly handle malformed Remote Desktop requests. Specifically, abnormally long data received by the Remote Desktop Protocol could cause the system to fail.
A reliable source has suggested that this issue may exist in the 'rdpwd.sys' RDP (Remote Desktop Protocol) driver. The cause of the issue may be a 'mov cl,[eax+1]' instruction that attempts to move data into the 'cl' register with the 'eax' register pointing to an invalid memory address, which will result in a page fault. This has not been confirmed by Symantec.
