4) Description of Vulnerability

Secunia Research has discovered a vulnerability in Autonomy KeyView,
which can be exploited by malicious people to cause a DoS (Denial of 
Service) and potentially compromise a vulnerable system.

The vulnerability is caused by an integer underflow error in the 
SpreadSheet Lotus 123 reader (wkssr.dll) when parsing the size of a 
specific record type. This can be exploited to cause a heap-based 
buffer overflow via a specially crafted file.

Successful exploitation may allow execution of arbitrary code.
