Fcron is a command scheduler with extended capabilities over cron
|
|
and anacron.

<p>
|
|
Due to design errors in the fcronsighup program, Fcron may allow a
|
|
local user to bypass access restrictions (CAN-2004-1031), view the
|
|
contents of root owned files (CAN-2004-1030), remove arbitrary files or
|
|
create empty files (CAN-2004-1032), and send a SIGHUP to any process. A
|
|
vulnerability also exists in fcrontab which may allow local users to
|
|
view the contents of fcron.allow and fcron.deny (CAN-2004-1033).
|
|

|
<impact type="normal">
|
|
<p>
|
|
A local attacker could exploit these vulnerabilities to perform a
|
|
Denial of Service on the system running Fcron.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>
|
|
Make sure the fcronsighup and fcrontab binaries are only
|
|
executable by trusted users.
|
|
</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>
|
|
All Fcron users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=sys-process/fcron-2.0.2"</code>
|
|
</resolution>
