VDE is an ethernet compliant virtual network that can be spawned over a set of physical computer over the Internet.
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.
A local attacker could escalate privileges to root.
There is no known workaround at this time.
All VDE users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=net-misc/vde-2.3.2-r4"
