Arch Linux Security Advisory ASA-201705-12
==========================================
Severity: High
Date : 2017-05-10
CVE-ID : CVE-2017-8422
Package : kauth
Type : privilege escalation
Remote : No
Link : https://security.archlinux.org/AVG-269
Summary
=======
The package kauth before version 5.33.0-2 is vulnerable to privilege
escalation.
Resolution
==========
Upgrade to 5.33.0-2.
# pacman -Syu "kauth>=5.33.0-2"
The problem has been fixed upstream but no release is available yet.
Workaround
==========
None.
Description
===========
KAuth <= 5.33.0 contains a logic flaw in which the service invoking
dbus 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, unprivileged attacker can escalate privileges to become root
on the affected host.
