This signature detects a remote stack-buffer overflow vulnerability in the Microsoft Word.

Additional Information

Microsoft Word is a word processor available for multiple platforms.

Word is prone to a remote stack-buffer overflow vulnerability when opening a specially crafted Word ('.doc') file. The problem occurs when parsing the File Information Block (FIB) structure in a Word document.

Attackers can exploit this issue by enticing victims into opening a malicious Word file.

Successful exploits can allow attackers to execute arbitrary code with the privileges of the user running the application.
