Subject: [PATCH 1/2] auditsc: audit_krule mask accesses need bounds checking
Date: Wed, 28 May 2014 23:09:58 -0400
Message-Id: <1401332999-15167-1-git-send-email-eparis@redhat.com>
X-Scanned-By: MIMEDefang 2.68 on 10.5.11.26

Precedence: bulk
List-ID: <stable.vger.kernel.org>
X-Mailing-List: stable@vger.kernel.org
From: Andy Lutomirski <luto@amacapital.net>
Fixes an easy DoS and possible information disclosure.
This does nothing about the broken state of x32 auditing.
eparis: If the admin has enabled auditd and has specifically loaded audit
rules. This bug has been around since before git. Wow...

I kept Sam's ack from v2, since v3 has only a trivial change.
Changes from v1: Remove core kbuild change
Changes from v2: Name the result .so files again, not .so.dbg
