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.
