Red Hat Security Advisory 2017-0403-01 - The kernel packages contain the Linux kernel, the core of any Linux operating system. Security Fix: A use-after-free flaw was found in the way the Linux kernel's Datagram Congestion Control Protocol implementation freed SKB 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.

Synopsis: Important: kernel security update
Advisory ID: RHSA-2017:0403-01
Product: Red Hat Enterprise Linux
Advisory URL: https://rhn.redhat.com/errata/RHSA-2017-0403.html
Issue date: 2017-03-02
CVE Names: CVE-2017-6074
=====================================================================

1. Summary:

An update for kernel is now available for Red Hat Enterprise Linux 7.1
Extended Update Support.

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.

2. Relevant releases/architectures:

Red Hat Enterprise Linux ComputeNode EUS (v. 7.1) - noarch, x86_64
Red Hat Enterprise Linux ComputeNode Optional EUS (v. 7.1) - x86_64
Red Hat Enterprise Linux Server EUS (v. 7.1) - noarch, ppc64, ppc64le, s390x, x86_64
Red Hat Enterprise Linux Server Optional EUS (v. 7.1) - ppc64, ppc64le, s390x, x86_64

3. Description:

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)

Red Hat would like to thank Andrey Konovalov (Google) for reporting this
issue.

4. Solution:

For details on how to apply this update, which includes the changes
described in this advisory, refer to:

https://access.redhat.com/articles/11258

The system must be rebooted for this update to take effect.

5. Bugs fixed (https://bugzilla.redhat.com/):

1423071 - CVE-2017-6074 kernel: use after free in dccp protocol
