Synopsis:	Moderate: systemtap security update
Issue date:	2011-07-25
CVE Names:	CVE-2011-2503

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

SL 5.x
