Bug#779195: kfreebsd-10: CVE-2015-1414: DoS via IGMP packet

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

Package: src:kfreebsd-10
Version: 10.1~svn274115-2
Severity: grave
Tags: security upstream patch

Hi,

A remote DoS was reported in FreeBSD's IGMP packet handling:
https://www.freebsd.org/security/advisories/FreeBSD-SA-15:04.igmp.asc

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

I don't know yet if this can be exploited over the public Internet
or only on a local network segment.

As a mitigation, the PF firewall can probably be configured to block
'proto igmp' packets before the kernel processes them.
