Bug#722337: kfreebsd-9: CVE-2013-5710: nullfs hardlinks across mounts

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

Package: src:kfreebsd-9
Version: 9.0-10+deb70.3
Severity: grave
Tags: security upstream
Control: found -1 kfreebsd-9/9.0~svn223109-0.1

http://security.FreeBSD.org/advisories/FreeBSD-SA-13:13.nullfs.asc

nullfs wrongly allows creating hard links between separate instances, as
long as they're based on the same underlying filesystem.  That
undermines security of chroot/jails depending on it for isolation.

kfreebsd-8 and kfreebsd-9 in wheezy will need the patch from r255443

kfreebsd-9 in jessie/sid will need updating to r255444 or later

kfreebsd-10 in experimental will need updating to r255442 or later
