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 < 3.5.2-r1 >= 3.5.2-r1
*>= 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
==========
