ZDI-09-035: Microsoft Word Document Stack Based Buffer Overflow
Vulnerability
http://www.zerodayinitiative.com/advisories/ZDI-09-035
June 10, 2009
- CVE ID: CVE-2009-0563
- Affected Vendors: Microsoft
- Affected Products: Microsoft Office Word
- Vulnerability Details: This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Microsoft Word. User interaction is required to exploit this vulnerability in that the target must visit a malicious page, open a malicious e-mail, or open a malicious file.
The specific flaw exists within the parsing of vulnerable tags inside a Microsoft Word document. Microsoft Word trusts a length field read from the file which is used to read file contents into a buffer allocated on the stack. When an invalid length is present, a stack based buffer overflow occurs, resulting in the ability to execute arbitrary code.
- Vendor Response: Microsoft has issued an update to correct this vulnerability. More details can be found at:
