<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.
|

|
<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>
