GLSA-200606-07 : Vixie Cron: Privilege Escalation

high Nessus Plugin ID 21680

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'
