Language:

Synopsis

The remote Gentoo host is missing one or more security-related patches.

Description

The remote host is affected by the vulnerability described in GLSA-201711-11 (VDE: Privilege escalation)

 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.

Solution

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