===================================================================== Red Hat Security Advisory
Synopsis: Important: kernel security and bug fix update Advisory ID: RHSA-2014:1872-01 Product: Red Hat Enterprise Linux Advisory URL: https://rhn.redhat.com/errata/RHSA-2014-1872.html Issue date: 2014-11-18 CVE Names: CVE-2014-5077 =====================================================================
1. Summary:
Updated kernel packages that fix one security issue and one bug are now available for Red Hat Enterprise Linux 6.4 Extended Update Support.
Red Hat Product Security has rated this update as having Important security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section.
2. Relevant releases/architectures:
Red Hat Enterprise Linux Compute Node Optional EUS (v. 6.4) - x86_64 Red Hat Enterprise Linux HPC Node EUS (v. 6.4) - noarch, x86_64 Red Hat Enterprise Linux Server EUS (v. 6.4) - i386, noarch, ppc64, s390x, x86_64 Red Hat Enterprise Linux Server Optional EUS (v. 6.4) - i386, ppc64, s390x, x86_64
3. Description:
The kernel packages contain the Linux kernel, the core of any Linux operating system.
* A NULL pointer dereference flaw was found in the way the Linux kernel's Stream Control Transmission Protocol (SCTP) implementation handled simultaneous connections between the same hosts. A remote attacker could use this flaw to crash the system. (CVE-2014-5077, Important)
This update also fixes the following bug:
* This update fixes several race conditions between PCI error recovery callbacks and potential calls of the ifup and ifdown commands in the tg3 driver. When triggered, these race conditions could cause a kernel crash. (BZ#1142568)
All kernel users are advised to upgrade to these updated packages, which contain backported patches to correct these issues. The system must be rebooted for this update to take effect.
4. Solution:
Before applying this update, make sure all previously released errata relevant to your system have been applied.
This update is available via the Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at https://access.redhat.com/articles/11258
To install kernel packages manually, use "rpm -ivh [package]". Do not use "rpm -Uvh" as that will remove the running kernel binaries from your system. You may use "rpm -e" to remove old kernels after determining that the new kernel functions properly on your system.
5. Bugs fixed (https://bugzilla.redhat.com/):
1122982 - CVE-2014-5077 Kernel: net: SCTP: fix a NULL pointer dereference during INIT collisions
