SystemTap is an instrumentation system for systems running the Linux
kernel. The system allows developers to write scripts to collect data
on the operation of the system.

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 a backported patch to correct this issue.
