Synopsis :

The remote Scientific Linux host is missing one or more security
updates.

Description :

Security Fix(es) :

- An out-of-bounds read/write access flaw was found in the
way QEMU's VGA emulation with VESA BIOS Extensions (VBE)
support performed read/write operations using I/O port
methods. A privileged guest user could use this flaw to
execute arbitrary code on the host with the privileges
of the host's QEMU process. (CVE-2016-3710)

- 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 results in
unbounded memory allocation on the host controlled by
the guest. (CVE-2016-5403)
