Stack-based buffer overflow in wp6sr.dll in the Autonomy KeyView SDK 10.4 and earlier, as used in IBM Lotus Notes, Symantec Mail Security (SMS) products, Symantec BrightMail Appliance products, and Symantec Data Loss Prevention (DLP) products, allows remote attackers to execute arbitrary code via a crafted Word Perfect Document (WPD) file.
The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
