FreeBSD : FreeBSD -- bhyve - privilege escalation vulnerability (a479a725-9adb-11e6-a298-14dae9d210b8)
High Nessus Plugin ID 94263
SynopsisThe remote FreeBSD host is missing a security-related update.
DescriptionAn unchecked array reference in the VGA device emulation code could potentially allow guests access to the heap of the bhyve process.
Since the bhyve process is running as root, this may allow guests to obtain full control of the hosts they are running on. Impact : For bhyve virtual machines with the 'fbuf' framebuffer device configured, if exploited, a malicious guest could obtain full access to not just the host system, but to other virtual machines running on the system.
SolutionUpdate the affected package.
