DESCRIPTION:
Multiple vulnerabilities have been reported in various VMware
products, which can be exploited by malicious, local users to gain
escalated privileges or cause a DoS (Denial of Service) or by
malicious people to compromise a vulnerable system.

1) An unspecified error can be exploited by a user with
administrative privileges in the guest system to cause a memory
corruption on a certain host process.

Successful exploitation may allow execution of arbitrary code on the
host system.

2) An unspecified error can be exploited within the guest system to
cause a host process to crash.

The vulnerabilities affect VMWare ESX 3.0.1, 3.0.0, 2.5.4, 2.5.3,
2.1.3, and 2.0.2, VMWare Workstation 6.0.0 and 5.5.4, VMWare Player
2.0.0 and 1.0.4, VMWare Server 1.0.3, and VMWare ACE 2.0.0 and
1.0.3.

3) An integer underflow error in the DHCP server can be exploited to
cause a stack-based buffer overflow via a specially crafted DHCP
packet.

4) An integer overflow error in the DHCP server can be exploited to
cause a stack-based buffer overflow via a specially crafted DHCP
packet.

5) Improper handling of malformed DHCP packets can be exploited to
execute arbitrary code via a specially crafted DHCP packet.

Successful exploitation of the vulnerabilities allow execution of
arbitrary code.

6) Improper starting of registered services can be exploited to gain
escalated privileges.

The vulnerabilities affect VMWare Workstation 6.0.0 and 5.5.4, VMWare
Player 2.0.0 and 1.0.4, VMWare Server 1.0.3, and VMWare ACE 2.0.0 and
1.0.3.
