Subject: kfreebsd-10: CVE-2015-2923: IPv6 Hop limit lowering via RA messages

Date: Tue, 07 Apr 2015 22:41:51 +0100

Package: src:kfreebsd-10
Version: 10.1~svn274115-3
Severity: grave
Tags: security

Hi,

A local-network DoS was reported in the IPv6 stack of FreeBSD:
https://www.freebsd.org/security/advisories/FreeBSD-SA-15:09.ipv6.asc
(the same issue as CVE-2015-2922 on Linux).

This affects all our kfreebsd-8, -9, -10 and -11 packages.

Debian GNU/kFreeBSD packages enable "accept_rtadv" by default, so are
vulnerable to this DoS unless that flag is manually disabled on an
interface, or IPv6 connectivity not used.
