<affected>
<package name="kde-base/arts" auto="yes" arch="*">
<unaffected range="ge">3.5.2-r1</unaffected>

<background>
<p>
aRts is a real time modular system for synthesizing audio used by KDE.
artswrapper is a helper application used to start the aRts daemon.
</p>
</background>
<description>
<p>
artswrapper fails to properly check whether it can drop privileges
accordingly if setuid() fails due to a user exceeding assigned resource
limits.
</p>
</description>
<impact type="high">
<p>
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.
</p>
</impact>
<workaround>
<p>
There is no known workaround at this time.
</p>
</workaround>
<resolution>
<p>
All aRts users should upgrade to the latest version:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose kde-base/arts</code>
</resolution>
