The remote Red Hat host is missing a security update.
An update for rhev-hypervisor7 is now available for RHEV 3.X
Hypervisor and Agents for RHEL-6 and RHEV 3.X Hypervisor and Agents
Red Hat Product Security has rated this update as having a security
impact of Important. A Common Vulnerability Scoring System (CVSS) base
score, which gives a detailed severity rating, is available for each
vulnerability from the CVE link(s) in the References section.
The rhev-hypervisor package provides a Red Hat Enterprise
Virtualization Hypervisor ISO disk image. The Red Hat Enterprise
Virtualization Hypervisor is a dedicated Kernel-based Virtual Machine
(KVM) hypervisor. It includes everything necessary to run and manage
virtual machines: A subset of the Red Hat Enterprise Linux operating
environment and the Red Hat Enterprise Virtualization Agent.
Security Fix(es) :
* A use-after-free flaw was found in the way the Linux kernel's
Datagram Congestion Control Protocol (DCCP) implementation freed SKB
(socket buffer) resources for a DCCP_PKT_REQUEST packet when the
IPV6_RECVPKTINFO option is set on the socket. A local, unprivileged
user could use this flaw to alter the kernel memory, allowing them to
escalate their privileges on the system. (CVE-2017-6074)
Red Hat would like to thank Andrey Konovalov (Google) for reporting
Note: Red Hat Enterprise Virtualization Hypervisor is only available
for the Intel 64 and AMD64 architectures with virtualization
