SYSTEMS AFFECTED
Win systems running Microsoft Office 95 and 97
PROBLEM
Alan Lustiger posted following. He discovered what looks like a
major hole in Microsoft Office (95 and 97) passworded files.
While the files are encrypted (and I know that the Office 95 file
encryption is laughably weak), *the file attachments are not.* So
if you attach a Visio picture or Excel spreadsheet to a passworded
Word file, they are saved in the clear. Any ASCII file viewer can
be used to easily verify this. Needless to say, one can get a lot
of information from attachments. This problem exists for both
Word and Excel, 95 and 97. However, this ISN't Office Fault; but
OLE one's. Still, you got a problem.
SOLUTION
Alan e-mailed to secure@microsoft.com and never received a reply
besides the boilerplate "if we consider this a security problem
we'll contact you within one business day, otherwise call
support."
So if you really want to safeguard your MS Office files, use a
third-party encryption package.
