VDE: Privilege escalation

VDE: Privilege escalation A vulnerability was discovered in VDE which may allow local users to gain root privileges. vde 2017-11-12 2017-11-12 603382 local 2.3.2-r4 2.3.2-r4

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"
