Red Hat has released a systemtap security update for Red Hat Enterprise Linux

[RHSA-2011:1089-01] Moderate: systemtap security update

=====================================================================
Red Hat Security Advisory

Synopsis: Moderate: systemtap security update
Advisory ID: RHSA-2011:1089-01
Product: Red Hat Enterprise Linux
Advisory URL: https://rhn.redhat.com/errata/RHSA-2011-1089.html
Issue date: 2011-07-25
CVE Names: CVE-2011-2503
=====================================================================

1. Summary:

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.

2. Relevant releases/architectures:

Red Hat Enterprise Linux (v. 5 server) - i386, ia64, ppc, s390x, x86_64
Red Hat Enterprise Linux Desktop (v. 5 client) - i386, x86_64

3. 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.

4. Solution:

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

This update is available via the Red Hat Network. Details on how to
use the Red Hat Network to apply this update are available at
https://access.redhat.com/kb/docs/DOC-11259

5. Bugs fixed (http://bugzilla.redhat.com/):

716489 - CVE-2011-2503 systemtap: signed module loading race condition

3. 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.

It was found that SystemTap did not perform proper module path sanity
checking if a user specified a custom path to the uprobes module, used
when performing user-space probing ("staprun -u"). A local user who is a
member of the stapusr group could use this flaw to bypass intended
module-loading restrictions, allowing them to escalate their privileges by
loading an arbitrary, unsigned module. (CVE-2011-2502)

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
backported patches to correct these issues.

4. Solution:

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

This update is available via the Red Hat Network. Details on how to
