Summary: Updated kernel packages that fix one security issue and one bug are now available for Red Hat Enterprise Linux 6.3 Extended Update Support. The Red Hat Security Response Team 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 EUS (v. 6.3) - noarch, x86_64 Red Hat Enterprise Linux Compute Node Optional EUS (v. 6.3) - x86_64 Red Hat Enterprise Linux Server EUS (v. 6.3) - i386, noarch, ppc64, s390x, x86_64 Red Hat Enterprise Linux Server Optional EUS (v. 6.3) - i386, ppc64, s390x, x86_64 3. Description: The kernel packages contain the Linux kernel, the core of any Linux operating system. * A flaw was found in the way the Linux kernel processed an authenticated COOKIE_ECHO chunk during the initialization of an SCTP connection. A remote attacker could use this flaw to crash the system by initiating a specially crafted SCTP handshake in order to trigger a NULL pointer dereference on the system. (CVE-2014-0101, Important) Red Hat would like to thank Nokia Siemens Networks for reporting this issue. This update also fixes the following bug: * Due to an incorrect call of the weak-modules script in the kernel spec file, the weak-modules directory was removed from the system when removing or upgrading certain kernel packages related to weak-modules, such as kernel-debug. With this update, the weak-modules call in the kernel spec file has been corrected, and the script now preserves the weak-modules directory on the system in this scenario. (BZ#1076599) 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/site/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.
