The Dispatch_Write function in proxy/dispatcher/idirectfbsurface_dispatcher.c in DirectFB 1.4.4 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via the Voodoo interface, which triggers an out-of-bounds write.
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.
