Hi -

On Monday, Tavis Ormandy kindly let us know of two serious problems in
the setuid-root /usr/bin/staprun program.  These have now been patched
in the git repo, and updates are being released for RHEL and Fedora.

Until you install the patches, one workaround would be to remove the
setuid bits from staprun (chmod u-s /usr/bin/staprun), and operate it
only as root.  After the patches, the main end-user difference will be
that current non-root 'stapdev' users (who are root-equivalent in
systemtap powers) would also have to be added to the 'stapusr'
(limited-privilege powers) group.

We are sorry for the inconvenience.

3. Description:

SystemTap is an instrumentation system for systems running the Linux
kernel, version 2.6. Developers can write scripts to collect data on the
operation of the system. staprun, the SystemTap runtime tool, is used for
managing SystemTap kernel modules (for example, loading them).

It was discovered that staprun did not properly sanitize the environment
before executing the modprobe command to load an additional kernel module.
A local, unprivileged user could use this flaw to escalate their
privileges. (CVE-2010-4170)

It was discovered that staprun did not check if the module to be unloaded
was previously loaded by SystemTap. A local, unprivileged user could use
this flaw to unload an arbitrary kernel module that was not in use.
(CVE-2010-4171)

Note: After installing this update, users already in the stapdev group must
be added to the stapusr group in order to be able to run the staprun tool.

Red Hat would like to thank Tavis Ormandy for reporting these issues.

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
use the Red Hat Network to apply this update are available at

                   Red Hat Security Advisory

Synopsis:          Moderate: systemtap security update
Advisory ID:       RHSA-2010:0895-01
Product:           Red Hat Enterprise Linux
Advisory URL:      https://rhn.redhat.com/errata/RHSA-2010-0895.html
Issue date:        2010-11-17
CVE Names:         CVE-2010-4170
=====================================================================

1. Summary:

Updated systemtap packages that fix one security issue are now available
for Red Hat Enterprise Linux 4.

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 AS version 4 - i386, ia64, ppc, x86_64
Red Hat Enterprise Linux Desktop version 4 - i386, x86_64
Red Hat Enterprise Linux ES version 4 - i386, ia64, x86_64
Red Hat Enterprise Linux WS version 4 - i386, ia64, x86_64

3. Description:

SystemTap is an instrumentation system for systems running the Linux
kernel, version 2.6. Developers can write scripts to collect data on the
operation of the system. staprun, the SystemTap runtime tool, is used for
managing SystemTap kernel modules (for example, loading them).

It was discovered that staprun did not properly sanitize the environment
before executing the modprobe command to load an additional kernel module.
A local, unprivileged user could use this flaw to escalate their
privileges. (CVE-2010-4170)

Note: On Red Hat Enterprise Linux 4, an attacker must be a member of the
stapusr group to exploit this issue. Also note that, after installing this
update, users already in the stapdev group must be added to the stapusr
group in order to be able to run the staprun tool.

Red Hat would like to thank Tavis Ormandy for reporting this issue.

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
http://kbase.redhat.com/faq/docs/DOC-11259

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

653604 - CVE-2010-4170 Systemtap: Insecure loading of modules
