Gibe worm poses as a Microsoft update

The E-mail message:


Microsoft Customer,

     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
