Microsoft Word Document Parsing Buffer Overflow Vulnerability
Be carefull with those .doc's !!
SECUNIA ADVISORY ID:
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 overflow.
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.
