Scientific Linux Security Update : qemu-kvm on SL7.x x86_64

This script is Copyright (C) 2016 Tenable Network Security, Inc.

Synopsis :

The remote Scientific Linux host is missing one or more security

Description :

Security Fix(es) :

- Quick Emulator(Qemu) built with the Block driver for
iSCSI images support (virtio-blk) is vulnerable to a
heap buffer overflow issue. It could occur while
processing iSCSI asynchronous I/O ioctl(2) calls. A user
inside guest could use this flaw to crash the Qemu
process resulting in DoS or potentially leverage it to
execute arbitrary code with privileges of the Qemu
process on the host. (CVE-2016-5126)

- Quick emulator(Qemu) built with the virtio framework is
vulnerable to an unbounded memory allocation issue. It
was found that a malicious guest user could submit more
requests than the virtqueue size permits. Processing a
request allocates a VirtQueueElement and therefore
causes unbounded memory allocation on the host
controlled by the guest. (CVE-2016-5403)
