Lynis Auditing Tool 2.3.3

Lynis is an auditing tool for Unix (specialists). It scans the system and available software to detect security issues. Beside security related information it will also scan for general system information, installed packages and configuration mistakes. This software aims in assisting automated auditing, software patch management, vulnerability and malware scanning of Unix based systems.

Red Hat Security Advisory 2016-1652-01

Red Hat Security Advisory 2016-1652-01 – KVM is a full virtualization solution for Linux on AMD64 and Intel 64 systems. The qemu-kvm-rhev package provides the user-space component for running virtual machines using KVM in environments managed by Red Hat Enterprise Virtualization Manager. Security Fix: Quick emulator 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.

Red Hat Security Advisory 2016-1654-01

Red Hat Security Advisory 2016-1654-01 – KVM is a full virtualization solution for Linux on AMD64 and Intel 64 systems. The qemu-kvm-rhev package provides the user-space component for running virtual machines using KVM in environments managed by Red Hat Enterprise Virtualization Manager. Security Fix: Quick Emulator built with the Block driver for iSCSI images support is vulnerable to a heap buffer overflow issue. It could occur while processing iSCSI asynchronous I/O ioctl 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.
