Synopsis
========

Multiple vulnerabilities in D-Bus might allow an attacker to overwrite
files with a fixed filename in arbitrary directories or conduct a
symlink attack.

Background
==========

D-Bus is a message bus system which processes can use to talk to each
other.

Affected packages
=================

-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 sys-apps/dbus < 1.10.18 >= 1.10.18

Description
===========

Multiple vulnerabilities have been discovered in D-Bus. Please review
the original report referenced below for details.

Impact
======

An attacker could possibly overwrite arbitrary files named "once" with
content not controlled by the attacker.

A local attacker could perform a symlink attack against D-Bus' test
suite.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All D-Bus users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose ">=sys-apps/dbus-1.10.18"

References
==========
