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"
References ==========
