From 94db3e1cb356a0d2de1753888ceb0eb767404ec4 Mon Sep 17 00:00:00 2001
From: Matthew Daley <mattjd@gmail.com>
Date: Tue, 10 Sep 2013 22:18:46 +1200
Subject: [PATCH] libxl: fix out-of-memory error handling in
libxl_list_cpupool
...otherwise it will return freed memory. All the current users of this
function check already for a NULL return, so use that.
Coverity-ID: 1056194
This is CVE-2013-4371 / XSA-70
