Bug#796996: kfreebsd-10: CVE-2015-5675: IRET privilege escalation

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

Package: kfreebsd-10
Version: 10.1~svn274115-9
Severity: grave
Tags: security upstream patch

Hi,

Local users can trigger a kernel panic, or possibly escalate privileges,
by exploiting a flaw in the IRET handler in kfreebsd-9 and -10:
https://www.freebsd.org/security/advisories/FreeBSD-SA-15:21.amd64.asc

kfreebsd-8 may also be affected, but that release no longer
has security support.

kfreebsd-11 was fixed long ago in SVN r275833.
