Synopsis
========

The artswrapper part of aRts allows local users to execute arbitrary
code with elevated privileges.

Background
==========

aRts is a real time modular system for synthesizing audio used by KDE.
artswrapper is a helper application used to start the aRts daemon.

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

-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 kde-base/arts lt; 3.5.2-r1 gt;= 3.5.2-r1
*gt;= 3.4.3-r1

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

artswrapper fails to properly check whether it can drop privileges
accordingly if setuid() fails due to a user exceeding assigned resource
limits.

Impact
======

Local attackers could exploit this vulnerability to execute arbitrary
code with elevated privileges. Note that the aRts package provided by
Gentoo is only vulnerable if the artswrappersuid USE-flag is enabled.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All aRts users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose kde-base/arts

References
