Red Hat Security Advisory 2013-0662-01 - 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.
