Moderate Advisory RHSA-2017-0869-01 for Kernel ICMP Issue in RHEL 6.7

red hat
Calendar Grey April 4, 2017
Scroller Redhat
Kernel upgrade and security patch classified as moderate for Red Hat Enterprise Linux 6.7 Extended Support.
An update for kernel is now available for Red Hat Enterprise Linux 6.7 Extended Update Support

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.

Summary

The kernel packages contain the Linux kernel, the core of any Linux operating system.
Security Fix(es):
* A flaw was found in the Linux networking subsystem where a local attacker with CAP_NET_ADMIN capabilities could cause an out-of-bounds memory access by creating a smaller-than-expected ICMP header and sending to its destination via sendto(). (CVE-2016-8399, Moderate)
Enhancement(s):
* Previously, the mpt3sas driver incorrectly checked the Transport Layer Retries (TLR) state even on Redundant Array Of Independent Discs (RAID) devices. Consequently, a kernel panic occurred when mpt3sas attempted to read from the RAID devices. With this update, mpt3sas has been fixed to check the TLR state only for non-RAID devices, and the kernel no longer panics under the described circumstances. (BZ#1427459)
