+ <title>Fcron: Multiple vulnerabilities</title>
+ <synopsis>
+ Multiple vulnerabilities in Fcron can allow a local user to potentially
+ cause a Denial of Service.

+ <affected>
+ <package name="sys-process/fcron" auto="yes" arch="*">
+ <unaffected range="rge">2.0.2</unaffected>

+ <background>
+ <p>
+ Fcron is a command scheduler with extended capabilities over cron
+ and anacron.
+ </p>
+ </background>
+ <description>
+ <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).
+ </p>
+ </description>
+ <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 &quot;&gt;=sys-process/fcron-2.0.2&quot;</code>
+ </resolution>
