Scientific Linux Security Update : kvm on SL5.x x86_64 (20160927)

high Nessus Plugin ID 93794

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)

Solution

Update the affected packages.
