Description:
A vulnerability has been reported in Kaspersky Labs Anti-Virus, which can be exploited by malicious, local users to gain escalated privileges.
A design error due to improper address space validation in the KLIN.sys and KLICK.sys device drivers when processing IOCTL 0x80052110 requests can be exploited via a specially crafted IRP structure passed to the vulnerable IOCTL handler.
Successful exploitation allows execution of arbitrary code with kernel-level privileges.
The vulnerability is reported in version 2.0.0.281 of the device drivers, which are included in Kaspersky Labs Anti-Virus 6.0.0.303. Other versions may also be affected.
Solution:
Update to version 2.0.0.333 of the device drivers via Kaspersky's Update service.
Provided and/or discovered by:
Rubén Santamarta, reversemode.com.
Changelog:
2006-10-20: Added Kaspersky Internet Security 6.x as affected.
