Subject: CVE-2017-15119 Qemu: DoS via large option request
Hello,
Quick Emulator(Qemu) built with the Network Block Device(NBD) server support
is vulnerable to a denial-of-service issue. It could occur if a client sent
large option requests, making server waste CPU time on reading up to 4G bytes.
A client could use this flaw to keep the NBD server from serving other
requests, resulting in DoS.
Upstream patch:
