<background>
<p>
Vixie Cron is a command scheduler with extended syntax over cron.
</p>
</background>
<description>
<p>
Roman Veretelnikov discovered that Vixie Cron fails to properly
check whether it can drop privileges accordingly if setuid() in
do_command.c fails due to a user exceeding assigned resource limits.
</p>
</description>
<impact type="high">
<p>
Local users can execute code with root privileges by deliberately
exceeding their assigned resource limits and then starting a command
through Vixie Cron. This requires resource limits to be in place on the
machine.
</p>
</impact>
<workaround>
<p>
There is no known workaround at this time.
</p>
</workaround>
<resolution>
<p>
All Vixie Cron users should upgrade to the latest version:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose ">=sys-process/vixie-cron-4.1-r9"</code>
</resolution>
