CVE-2017-15118

A stack-based buffer overflow vulnerability was found in NBD server
implementation in qemu before 2.11 allowing a client to request an export
name of size up to 4096 bytes, which in fact should be limited to 256
bytes, causing an out-of-bounds stack write in the qemu process. If NBD
server requires TLS, the attacker cannot trigger the buffer overflow
without first successfully negotiating TLS.
