If NBD server requires TLS, the attacker cannot trigger the buffer overflow without first successfully negotiating TLS.", "A stack-based buffer overflow vulnerability was found in NBD server implementation in qemu allowing a client to request an export name of size up to 4096 bytes, which in fact should be limited to 256 bytes, allowing causing an out-of-bounds stack write in the qemu process.
