Synopsis: Moderate: sudo security update
Issue Date: 2012-07-16
CVE Numbers: CVE-2012-2337

The sudo (superuser do) utility allows system administrators to give
certain users the ability to run commands as root.

A flaw was found in the way the network matching code in sudo handled
multiple IP networks listed in user specification configuration directives.
A user, who is authorized to run commands with sudo on specific hosts,
could use this flaw to bypass intended restrictions and run those commands
on hosts not matched by any of the network specifications. (CVE-2012-2337)

All users of sudo are advised to upgrade to this updated package, which
contains a backported patch to correct this issue.
