DESCRIPTION:
ADLab has discovered a vulnerability in DAEMON Tools, which can be
exploited by malicious, local users to cause a DoS (Denial of
Service) and potentially gain escalated privileges.

The vulnerability is caused due to an indexing error when processing
the 0x00222850 IOCTL in dtsoftbus01.sys. This can be exploited to
write a DWORD value into arbitrary kernel memory.

Successful exploitation may allow execution of arbitrary code with
SYSTEM privileges.

The vulnerability is confirmed in version 4.41.3.0173. Other versions
may also be affected.

SOLUTION:
Update to version 4.45.3.0297.

PROVIDED AND/OR DISCOVERED BY:
ADLab, VenusTech via Secunia.
