[GLSA-200606-07] Vixie Cron: Privilege Escalation

Vulnerability Assessment Summary
Vixie Cron: Privilege Escalation

Detailed Explanation for this Vulnerability Assessment
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 rights accordingly if setuid() in
do_command.c fails due to a user exceeding assigned resource limits.

Impact

Local users can execute code with root rights 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.
