Problem description:
        Some time ago, a vulnerability was discovered that allowed for root
        access through ptrace call in the linux kernel. This was
        originally considered fixed in a previous patch, but as it turns
        out, it wasn't. This is fixed in kernel version 2.2.19.

  We recommend all systems which has this package installed to be upgraded.
  Please see the Kernel Upgrade Howto, available from
