This script is Copyright (C) 2017 Tenable Network Security, Inc.


Synopsis :

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

Description :

From Red Hat Security Advisory 2017:0293 :

An update for kernel is now available for Red Hat Enterprise Linux 6.

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 kernel packages contain the Linux kernel, the core of any Linux
operating system.

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, Important)
