This script is Copyright (C) 2004-2014 Tenable Network Security, Inc.


Synopsis :

The remote Gentoo host is missing one or more security-related
patches.

Description :

The remote host is affected by the vulnerability described in GLSA-200411-27
(Fcron: Multiple vulnerabilities)

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 :

A local attacker could exploit these vulnerabilities to perform a
Denial of Service on the system running Fcron.

Workaround :

Make sure the fcronsighup and fcrontab binaries are only
executable by trusted users.

Solution :

All Fcron users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose '>=sys-process/fcron-2.0.2'

Risk factor :

High / CVSS Base Score : 7.2
