The dirapi.dll module in Adobe Shockwave Player before 11.5.9.620 allows attackers to execute arbitrary code or cause a denial of service (memory corruption) via a Director movie with an IFWV chunk with a size field of 0, which is used in the calculation of a file offset and causes invalid data to be used as a loop counter, triggering a heap-based buffer overflow, a different vulnerability than CVE-2010-2587 and CVE-2010-2588.
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.
