NVD Description

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

QEMU, when built with the Pseudo Random Number Generator (PRNG) back-end support, allows local guest OS users to cause a denial of service (process crash) via an entropy request, which triggers arbitrary stack based allocation and memory corruption.
