Heap-based buffer overflow in the OLE importer in OpenOffice.org before 2.4 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via an OLE file with a crafted DocumentSummaryInformation stream.
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.
