Who is Vulnerable?
Vulnerability Description The Microsoft Help Workshop is a development tool to create Help (HLP) files for Windows based applications. Help Workshop uses project (HPJ) and content (CNT) files, along with other resource to compile the final help file that can be viewed using the Microsoft Windows Help program. A buffer overflow vulnerability has been found in the Microsoft Help Workshop product. The flaw is created by insufficient boundary checks of strings supplied in Help Content (CNT) files. A malicious user may construct a CNT file that will result in the diversion of the process flow of the vulnerable application. In an attack case where code injection is not successful, the affected application that is parsing the malicious CNT file may terminate abnormally. In a more sophisticated attack where code injection is successful, the behavior of the target host is entirely dependent on the intended function of the injected code. The code in such a case would execute within the security context of the currently logged in user.
