A local attacker can send a malicious request to generate a denial
of service.
Gravity: 1/4
Consequences: denial of service of service
Provenance: user shell
Means of attack: no proof of concept, no attack
Ability of attacker: expert (4/4)
Confidence: confirmed by the editor (5/5)

Creation date: 20/08/2008
Identifier: VIGILANCE-VUL-8042
IMPACTED PRODUCTS
– VMware Workstation [confidential versions]
DESCRIPTION
The "VMware workstation" system uses an "hcmon.sys" driver to
monitor USB.
This module is vulnerable because it does not sanitize correctly
arguments from "METHOD_NEITHER" user mode.
The IOCTL function is used to control peripherals such as USB
ports.
A local attacker can therefore send a malicious IOCTL request to
generate a denial of service.
