Medium Nessus Plugin ID 92859

Synopsis

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

Description

Security Fix(es) :

- 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)
