Stack-based buffer overflow in fprintf in musl before 0.8.8 and earlier allows context-dependent attackers to cause a denial of service (crash) or possibly execute arbitrary code via a long string to an unbuffered stream such as stderr.
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.
