this is the latest version of security update, the
known security vulnerabilities affecting Internet Explorer and
MS Outlook/Express as well as six new vulnerabilities, and is
discussed in Microsoft Security Bulletin MS02-005. Install now to
protect your computer from these vulnerabilities, the most serious of which
could allow an attacker to run code on your computer.
Description of several well-know vulnerabilities:
- - "Incorrect MIME Header Can Cause IE to Execute E-mail Attachment"
vulnerability. If a malicious user sends an affected HTML e-mail or
hosts an affected e-mail on a Web site, and a user opens the e-mail or
visits the Web site, Internet Explorer automatically runs the executable
on the user's computer.
- - A vulnerability that could allow an unauthorized user to learn the location
of cached content on your computer. This could enable the unauthorized
user to launch compiled HTML Help (.chm) files that contain shortcuts to
executables, thereby enabling the unauthorized user to run the executables
on your computer.
- - A new variant of the "Frame Domain Verification" vulnerability could enable a
malicious Web site operator to open two browser windows, one in the Web site's
domain and the other on your local file system, and to pass information from
your computer to the Web site.
- - CLSID extension vulnerability. Attachments which end with a CLSID file extension
do not show the actual full extension of the file when saved and viewed with
Windows Explorer. This allows dangerous file types to look as though they are simple,
harmless files - such as JPG or WAV files - that do not need to be blocked.
Versions of Windows no earlier than Windows 95.
This update applies to:
Versions of Internet Explorer no earlier than 4.01
Versions of MS Outlook no earlier than 8.00
Versions of MS Outlook Express no earlier than 4.01

This is Bob now. This clever bit of Social Engineering was to get you
to load the virus q216309.exe that was its attachment. It did show as
being from "Microsoft Corporation Security Center" <rdquest12 at microsoft.com>
which cleverly listed a return email address at Microsoft (and I'm not
dumb enough to run binaries from unconfirmed sources).
I recognized it as a virus only because I'm not on any Microsoft customer
list and my analysis of the headers showed it as being sent from
the University of California at Davis.
Microsoft's Security people cryptographically sign all of their email
with PGP. Don't even think of trusting any email containing possibly
dangerous attachments without a valid signature. I'm working on an
virus filter as an add on to my Firewall/VPN products.
