Stable kernels 3.0.66 and 3.4.33

The 3.4.33 and 3.0.66 stable kernel updates are available. These are single-patch updates fixing a buffer overflow in the printk() subsystem. According to the patch fixing the problem, the overflow can be triggered from (privileged) user space to freeze the kernel; worse outcomes might be possible. Kernels 3.5 and newer are not vulnerable due to the reworking of printk(); the bug evidently made its first appearance in 3.0.
