NVD Description

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

An assertion failure issue was found in the Network Block Device(NBD) Server in all QEMU versions before QEMU 5.0.1. This flaw occurs when an nbd-client sends a spec-compliant request that is near the boundary of maximum permitted request length. A remote nbd-client could use this flaw to crash the qemu-nbd server resulting in a denial of service.
