RHSA-2014:0678: Important: kernel security update
First published: Tue Jun 10 2014(Updated: )
The kernel packages contain the Linux kernel, the core of any Linux<br>operating system.<br><li> A race condition flaw, leading to heap-based buffer overflows, was found</li> in the way the Linux kernel's N_TTY line discipline (LDISC) implementation<br>handled concurrent processing of echo output and TTY write operations<br>originating from user space when the underlying TTY driver was PTY.<br>An unprivileged, local user could use this flaw to crash the system or,<br>potentially, escalate their privileges on the system. (CVE-2014-0196,<br>Important)<br>All kernel users are advised to upgrade to these updated packages, which<br>contain a backported patch to correct this issue. The system must be<br>rebooted for this update to take effect.<br>
