Red Hat: 2011:1089-01: systemtap: Moderate Advisory
Summary
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.
