Detail

Problem Description:

An update for kernel is now available for Red Hat Enterprise Linux 6.5 Advanced Update Support and Red Hat Enterprise Linux 6.5 Telco 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 Server AUS (v. 6.5) - noarch, x86_64 Red Hat Enterprise Linux Server Optional AUS (v. 6.5) - x86_64 Red Hat Enterprise Linux Server Optional TUS (v. 6.5) - x86_64 Red Hat Enterprise Linux Server TUS (v. 6.5) - noarch, 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
