Description:

    Previous versions of the kernel package are vulnerable to one     local user Denial of Service attack in which local users can     trigger a kernel stack overflow using the netlink layer, and to one     remote Denial of Service attack in which if IPv6 routing has been     configured, a remote user can cause the system to use all available     network bandwidth by sending a specially-crafted IPv6 packet.     

    In addition, several issues have been resolved that caused some     systems to have difficulty booting: attempting to initialize the     Intel random number generator caused some recent systems to hang     during boot, and NUMA capability was also causing some systems to     hang during boot and so has been disabled on x86, where it is     generally not needed.     

    A system reboot is required to resolve these issues.
