GLSA-200411-27 : Fcron: Multiple vulnerabilities

high Nessus Plugin ID 15768

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'
