The remote Fedora host is missing a security update.

Fix for CVE-2013-2207 may break chroots if their devpts was not
mounted correctly. Fix is to mount the devpts correctly with gid=5.

Note that Tenable Network Security has extracted the preceding
description block directly from the Fedora security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.
