GLSA-200606-07 : Vixie Cron: Privilege Escalation

This script is Copyright (C) 2006-2014 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-200606-07
(Vixie Cron: Privilege Escalation)

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 :

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.

Workaround :

There is no known workaround at this time.

Solution :

All Vixie Cron users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose '>=sys-process/vixie-cron-4.1-r9'

Risk factor :

High / CVSS Base Score : 7.2
