Protection Provided by:	Security Gateway R81, R80, R77, R75, R71, R70, R65
Who is Vulnerable?
Vulnerability Description	An elevation of privilege vulnerability exists in the Windows Kernel due to the way the kernel handles certain exceptions. The Windows Kernel is the core of the operating system. It provides system level services such as device management and memory management, allocates processor time to processes, and manages error handling. An attacker may exploit this vulnerability via a specially crafted application. The vulnerability is due to a design weakness in the Windows kernel when handling certain exceptions. A remote attacker could trigger this flaw by using a specially crafted 16-bit program in the affected system. Successfully exploitation of this vulnerability could allow the attacker to take complete control of an affected system. There are cases in which certain traffic, although not intended for malicious use, is very unsafe, since it may transfer shellcode which is undetectable by IPS.
