NVD Description

Note: Versions mentioned in the description apply only to the upstream qemu-block-rbd package and not the qemu-block-rbd package as distributed by Oracle. See How to fix? for Oracle:7 relevant fixed versions and status.

The Network Block Device (NBD) server in Quick Emulator (QEMU) before 2.11 is vulnerable to a denial of service issue. It could occur if a client sent large option requests, making the server waste CPU time on reading up to 4GB per request. A client could use this flaw to keep the NBD server from serving other requests, resulting in DoS.
