DESCRIPTION:
A vulnerability has been discovered in Look 'n' Stop Firewall, which
can be exploited by malicious, local users to cause a DoS (Denial of
Service).
The vulnerability is caused due to an error in the "lnsfw1.sys"
driver when handling the 80000064h IOCTL. This can be exploited to
cause an assertion error and crash the kernel via a specially crafted
input buffer passed to the IOCTL.
The vulnerability is confirmed in version 2.07. Other versions may
also be affected.
SOLUTION:
Restrict access to trusted users only.
