The kernel packages contain the Linux kernel, the core of any Linux
operating system.

This update fixes the following security issue:

A race condition was found in the way the Linux kernel’s ptrace
implementation handled PTRACE_SETREGS requests when the debuggee was woken
due to a SIGKILL signal instead of being stopped. A local, unprivileged
user could use this flaw to escalate their privileges. (CVE-2013-0871,
Important)

Users should 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.
