It was discovered that Gentoo’s default VDE installation suffered from a privilege escalation vulnerability in the init script. This script calls an unsafe ‘chown’ command which gives members from “qemu”
group root privileges.
Impact :

A local attacker could escalate privileges to root.

All VDE users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=net-misc/vde-2.3.2-r4'
