Synopsis
========
A vulnerability was discovered in VDE which may allow local users to
gain root privileges.
Background
==========
VDE is an ethernet compliant virtual network that can be spawned over a
set of physical computer over the Internet.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 net-misc/vde < 2.3.2-r4 >= 2.3.2-r4
Description
===========
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.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All VDE users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=net-misc/vde-2.3.2-r4"
