iDefense Security Advisory 03.17.09 - Remote exploitation of a stack-based buffer overflow in Autonomy Inc's KeyView SDK allows attackers to execute arbitrary code with the privileges of the current user. This vulnerability exists within the "wp6sr.dll" which implements the processing of Word Perfect Documents. When processing certain records, data is copied from the file into a fixed-size stack buffer without ensuring that enough space is available. By overflowing the buffer, an attacker can overwrite control flow structures stored on the stack. iDefense confirmed that this vulnerability exists within Lotus Notes 8 installed on a Windows XP SP3 machine. All applications which utilize the Autonomy KeyView SDK to process Word Perfect Documents are suspected to be vulnerable.
