How could OS X, with it's unix bullet proof security, allow a lowly
application to circumvent security??

"VMware bug allows Windows hack to attack Macs"

If the title weren't enough to answer your question, reading the
article should have:

"This is indeed a guest-to-host exploit," Kortchinsky
said in an e-mail today. "It uses several
vulnerabilities in the 'Display functions' (as VMware
put it) that allow [someone] to read and write
arbitrary memory in the host. Thus the guest can run
some code on the host, effectively bypassing ASLR and
DEP on Vista SP1."

The same tactics can be employed against a guest
operating system -- say, Windows XP -- running in
Fusion on a Mac powered by Apple's Mac OS X,
Kortchinsky confirmed. "The vulnerability is also
present in VMware Fusion and as such would allow a
guest (Windows or Linux) to run code on the Mac OS X
host," he said. "We didn't implement this exploit
though, but will probably in a near future."


VMware and Windows are at the bottom of the problem, not flaws in OSX
security.
"The vulnerability is also present in VMware
Fusion and as such would allow a guest (Windows or
Linux) to run code on the Mac OS X host," he said.

Why did you focus on that one sentence and ignore everything else I
quoted to you?

There is a flaw if OS X allows this to happen when an ordinary user
runs it without an Administrator prompt.

Most ordinary users don't run a guest OS in a virtual machine, and the
flaw is in Windows and the VM, not in OS X.

Who else would be running the Guest OS? God?

Not an ordinary user, the person you expected to be affected by this.

I expect OS X (not
"Windows" to prompt me for a password if anything is done that could
harm the system.

Running a virtual machine isn't the same thing as running an
application. I don't see how you expect Mac OS X to manage the operation
of a foreign OS running on virtual hardware!
