  kernel. The system allows developers to write scripts to collect data on
  the operation of the system.

  It was found that SystemTap did not perform proper module path sanity
  checking if a user specified a custom path to the uprobes module, used
  when performing user-space probing ("staprun -u"). A local user who is a
  member of the stapusr group could use this flaw to bypass intended
  module-loading restrictions, allowing them to escalate their privileges by
  loading an arbitrary, unsigned module. (CVE-2011-2502)

  A race condition flaw was found in the way the staprun utility performed
  module loading. A local user who is a member of the stapusr group could
  use this flaw to modify a signed module while it is being loaded,
  allowing them to escalate their privileges. (CVE-2011-2503)

  SystemTap users should upgrade to these updated packages, which contain
  backported patches to correct these issues.";
