RHSA-2011:1089 - Moderate: systemtap security update


Synopsis

Moderate: systemtap security update

Type/Severity

Security Advisory Moderate

Topic

Updated systemtap packages that fix one security issue are now available for Red Hat Enterprise Linux 5.

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.

Description

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.

Solution

Before applying this update, make sure all previously-released errata relevant to your system have been applied.
