Summary: Updated kernel packages that fix one security issue 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 race condition flaw, leading to heap-based buffer overflows, was found in the way the Linux kernel's N_TTY line discipline (LDISC) implementation handled concurrent processing of echo output and TTY write operations originating from user space when the underlying TTY driver was PTY. An unprivileged, local user could use this flaw to crash the system or, potentially, escalate their privileges on the system. (CVE-2014-0196, Important) All kernel users are advised to upgrade to these updated packages, which contain a backported patch to correct this issue. 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.
