CWE-331  (opens in a new tab)

How to fix?

Upgrade Ubuntu:15.10 qemu to version 1:2.3+dfsg-5ubuntu9.4 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream qemu package and not the qemu package as distributed by Ubuntu. See How to fix? for Ubuntu:15.10 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.
