DESCRIPTION:
Some security issues have been reported in various VMware products,
which can be exploited by malicious, local users in a guest virtual
machine to disclose system information and gain escalated
privileges.

1) An error within the mount.vmhgfs utility can be exploited to
determine whether or not a certain file or directory exists on the
host system.

2) A race condition within the mount.vmhgfs utility can be exploited
to mount arbitrary directories and e.g. gain escalated privileges.

3) An error within the mount.vmhgfs utility allows write access to
arbitrary files and can be exploited to gain escalated privileges.

Note: The security issues do not affect Windows-based guest systems.
Security issue #3 only affects Solaris and FreeBSD guest systems.

SOLUTION:
Update to a fixed version or apply patches. Install updated VMware
Guest Tools.
