Heap-based buffer overflow in an unspecified library in Autonomy KeyView 10.4 and 10.9, as used in multiple IBM, Symantec, and other products, allows remote attackers to execute arbitrary code via a crafted compound file, as demonstrated using a Quattro Pro file, which is not properly handled by the Quattro speed reader (qpssr.dll).
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.
