DESCRIPTION:
Secunia Research has discovered two vulnerabilities in GEAR CD DVD
Filter Driver, which can be exploited by malicious, local users to
cause a DoS (Denial of Service).

1) An array-indexing error when accessing a table of pointers can be
exploited to access invalid memory and cause the kernel to crash via
a specially crafted 0x00222018 IOCTL.

2) A second array-indexing error when accessing a table of pointers
can be exploited to access invalid memory and cause the kernel to
crash via a specially crafted 0x0022201C IOCTL.

The vulnerabilities are confirmed in the following products (other
versions may also be affected):
* GEAR CD DVD Filter Driver version 2.2.0.1.
* GEAR ISO Burn version 1.7.1.

SOLUTION:
Apply patch via the driver installer package version 4.018.3.
