local privilege escalation issue." );

"The version of Kaspersky Anti-Virus installed on the remote host allows
a local attacker to execute arbitrary code with kernel privileges by
passing a specially crafted Irp structure to an IOCTL handler used by
the KLIN and KLICK device drivers.  By leveraging this flaw, a local
attacker may be able to gain complete control of the affected system." );
