GLSA-201706-29 : KAuth and KDELibs: Privilege escalation

This script is Copyright (C) 2017 Tenable Network Security, Inc.


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-201706-29
(KAuth and KDELibs: Privilege escalation)

KAuth and KDELibs contains a logic flaw in which the service invoking
D-Bus is not properly checked. This allows spoofing the identity of the
caller and with some carefully crafted calls can lead to gaining root
from an unprivileged account.

Impact :

A local attacker could spoof the identity of the caller invoking D-Bus,
possibly resulting in gaining privileges.

Workaround :

There is no known workaround at this time.

# emerge --ask --oneshot --verbose '>=kde-frameworks/kauth-5.29.0-r1'
All KDELibs users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose '>=kde-frameworks/kdelibs-4.14.32'
