IE and Outlook 5.x allow executing arbitrary programs using .eml files

Description:
There is a vulnerability in IE and Outlook 5.x for Win9x/WinNT (probably
others) which allows executing arbitrary programs using .eml files.

Would this happen to apply to other web browsers, e.g., Netscape?


Netscape Communicator is not affected, don't know for other browsers.

Details:
The problem is creating files in the TEMP directory with known name and
arbitrary content.

How does the file get there?  Do all .eml files create temp files?  I
assume another work-around would be to have a user-specific temp directory,
such as Windows 2000 uses.


The file is created by IE or some of its components. AFAIK not all .eml
files create temp files.
User specific temp directory is better than the default one.
