SYNTHESIS OF THE VULNERABILITY
An attacker, inside a guest system, can corrupt the memory via
bhyve of FreeBSD, in order to escalate his privileges on the host
system.
Impacted products: FreeBSD.
Severity: 2/4.
Creation date: 26/10/2016.
DESCRIPTION OF THE VULNERABILITY
The FreeBSD product offers a bhyve hypervisor.

memory via bhyve of FreeBSD, in order to escalate his privileges
on the host system.
