Description:
Piotr Bania has reported a vulnerability in SoftICE, 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 DbgMsg.sys driver and can be exploited via a specially crafted "int 2dh" call with an invalid debug message pointer.
Successful exploitation crashes the system and does not require that SoftICE is active.
The vulnerability has been reported in SoftICE included in DriverStudio versions 3.1 and 3.2. Other versions may also be affected.
Solution:
Grant only trusted users access to affected systems.
