-- CVE ID:

-- Affected Vendor:
Verity

-- Affected Products:
KeyView SDK

-- Vulnerability Details:
Several vulnerabilities exist in the popular Verity KeyView SDK used in

lies when copying user supplied data to a stack based buffer without
any boundary conditions.

The following file formats have been identified as vulnerable:

Adobe Acrobat FrameMaker - .mif
Applix Words - .aw
Microsoft Rich Text Format - .rtf
Portable Executable - .exe
Dynamic Link Library - .dll
Applix Presents - .ag
Microsoft Word - .doc
