Heap-based buffer overflow in OpenOffice.org (aka StarOffice) 1.1.x up to 1.1.5 and 2.0.x before 2.0.3 allows user-assisted attackers to execute arbitrary code via a crafted OpenOffice XML document that is not properly handled by (1) Calc, (2) Draw, (3) Impress, (4) Math, or (5) Writer, aka "File Format / Buffer Overflow Vulnerability."
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.
