This article discusses the W32.Gibe@mm virus that may affect the operation of your computer. The information in this article is provided as-is without warranty of any kind. Microsoft does not provide software to stop virus infections or to cure infected computers. You may want to contact an antivirus software manufacturer for more information about how to remove a virus from your computer and about how to prevent future infections. If your computer has been infected, it may be open to additional forms of attack. Microsoft recommends that you rebuild infected Internet-facing servers (servers that function without a firewall or other protection) by following the guidelines that are published on the CERT
(http://www.cert.org/)Web site. Microsoft also recommends that you rebuild any other computers that are at risk because of their proximity to infected computers before you place them back in service.
The W32.Gibe@mm virus is a mass-mailing e-mail worm program that uses Microsoft Outlook as well as a built-in Simple Mail Transport Protocol (SMTP) engine to spread.
IMPORTANT: Microsoft does not distribute programs or updates by using e-mail messages.
The W32.Gibe@mm virus affects Outlook, Microsoft Outlook Express, and Web-based e-mail programs. This virus arrives in an e-mail message with the following characteristics:

Subject: Internet Security Update
This is the latest version of security update, the "7 Mar 2002 Cumulative Patch" update which eliminates all 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
