Additional Information

Autonomy KeyView Filter is a component used in multiple applications. It adds filtering, viewing, and exporting of documents to web-ready HTML or valid XML.

Autonomy KeyView is prone to a stack-based buffer-overflow vulnerability when processing tag information in an Applix document.

An attacker can exploit this issue by enticing an unsuspecting victim to open a malicious file or email attachment.

Successful exploits can allow attackers to execute arbitrary code with the privileges of the user running the application. Failed exploit attempts will result in a denial-of-service condition.
