Multiple integer overflows in OpenOffice.org (OOo) 2.x before 2.4.2 allow remote attackers to execute arbitrary code via crafted EMR records in an EMF file associated with a StarOffice/StarSuite document, which trigger a heap-based buffer overflow.
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.
