Microsoft Word Document Parsing Buffer Overflow Vulnerability
DoS, System access
Microsoft Office 2000
Microsoft Office XP
Microsoft Word 2000
Microsoft Word 2002
HexView has discovered a vulnerability in Microsoft Word, which can
be exploited by malicious people to cause a DoS (Denial of Service)
and potentially compromise a user's system.
The vulnerability is caused due to an input validation error within
the parsing of document files and may lead to a stack-based buffer
This can be exploited to crash the process when the user opens a
specially crafted document. However, due to the nature of the
problem, execution of arbitrary code may potentially also be
possible, though it has not been proven.
The vulnerability has been confirmed in Microsoft Word 2000, but has
also been reported in Microsoft Word 2002.
Open trusted documents only.
For Internet Explorer users, documents on web sites can be opened
automatically in the browser, unless the security level for the
"Internet" security zone is set to "High" or the "File download"
setting has been disabled.
