The Red Hat Security Response Team has rated this update as having moderate security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section.

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.

Update the affected systemtap packages.
