Integer overflow in the isofs_real_read_zf function in isofs.c in FuseISO 20070708 might allow remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact via a large ZF block size in an ISO file, leading to 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.
