RHSA-2014:0678: Important: kernel security update
The kernel packages contain the Linux kernel, the core of any Linuxoperating system. A race condition flaw, leading to heap-based buffer overflows, was found in the way the Linux kernel's NTTY line discipline (LDISC) implementationhandled concurrent processing of echo output and TTY write operationsoriginating 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, whichcontain a backported patch to correct this issue. The system must berebooted for this update to take effect.
