CVE Author: NIST National Vulnerability Database
CVSS Base Vector:
AV:L/AC:L/Au:N/C:N/I:N/A:C
Detection Type:
Linux Distribution Package
Summary:
Check the version of qemu-guest-agent
Detection Method:
Checks if a vulnerable version is present on the target host.
Technical Details:
KVM (Kernel-based Virtual Machine) is a
full virtualization solution for Linux on AMD64 and Intel 64 systems.
The qemu-kvm Linux Distribution Packages provide the user-space component for running virtual machines
using KVM.
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)
Red Hat would like to thank hongzhenhao (Marvel Team) for reporting this
issue.
Affected Versions:
qemu-guest-agent on CentOS 6

What's vulnerability management?
Vulnerability management is the process in which vulnerabilities in IT are identified and the risks of these vulnerabilities are evaluated. This evaluation leads to correcting the vulnerabilities and removing the risk or a formal risk acceptance by the management of an organization. The term vulnerability management is often confused with vulnerability scanning. Despite the fact both are related, there is an important difference between the two. Vulnerability scanning consists of using a computer program to identify vulnerabilities in networks, computer infrastructure or applications. Vulnerability management is the process surrounding vulnerability scanning, also taking into account other aspects such as risk acceptance, remediation etc. Source: "Implementing a Vulnerability Management Process".
