Stack-based buffer overflow in the zfile_gunzip function in zfile.c in WinUAE 1.4.4 and earlier allows user-assisted remote attackers to execute arbitrary code via a long filename in a gzipped archive, such as a (1) gz, (2) adz, (3) roz, or (4) hdz archive in a compressed floppy disk image.
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.
