Bug#717958: kfreebsd-9: CVE-2013-4851: nfsserver applies wrong credentials

[Steven Chamberlain <steven@pyro.eu.org>]

Package: src:kfreebsd-9
Version: 9.0-10+deb70.2
Severity: grave
Tags: security upstream
Control: found -1 kfreebsd-9/9.0~svn223109-0.1

The FreeBSD NFS server implementation applies the wrong group
credentials (supplied by the client) to an authenticated NFS session in
specific configurations (exports defined using -mapall or -maproot with
-network or -host).

This was fixed in kfreebsd-10 since r244226, but the security
implications for kfreebsd-9 and kfreebsd-8 have just been realised.
