CVE-2016-2858 (opens in a new tab)Amendment
The Ubuntu security team deemed this advisory irrelevant for Ubuntu:12.04.
NVD Description
Note: Versions mentioned in the description apply only to the upstream qemu-kvm package and not the qemu-kvm package as distributed by Ubuntu.
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.
