DESCRIPTION:
Two weaknesses have been discovered in GEAR CD DVD Filter Driver,
which can be exploited by malicious, local users to cause a DoS
(Denial of Service).

2) An array indexing error in the GEARAspiWDM.sys driver when
accessing a table of pointers can be exploited to access invalid
memory and cause a crash via a specially crafted 0X00222008 IOCTL.

2) A second array indexing error in the GEARAspiWDM.sys driver when
accessing a table of pointers can be exploited to access invalid
memory and cause a crash via a specially crafted 0X00222010 IOCTL.

The weaknesses 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:
Restrict access to trusted users only.

PROVIDED AND/OR DISCOVERED BY:
Originally reported in Symantec Backup Exec System Recovery by Stefan
LE BERRE (Heurs).
