Title:	D-Bus: Multiple vulnerabilities
Date:	06/06/2017
Bugs:	#611392
ID:	201706-05

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	Architecture(s)
sys-apps/dbus	< 1.10.18	>= 1.10.18	All supported architectures

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"
