SecurityTracker Alert ID:  1023667
SecurityTracker URL:  http://securitytracker.com/id/1023667
CVE Reference:   CVE-2010-0411   (Links to External Site)
Date:  Mar 1 2010
Impact:   Denial of service via local system, Execution of arbitrary code via local system, Root access via local system
Fix Available:  Yes  Vendor Confirmed:  Yes  

Description:   A vulnerability was reported in SystemTap. A local user can obtain elevated privileges on the target system.

A local user can trigger a buffer overflow in __get_argv() to cause the target system to crash (if the calling script runs with root privileges) or potentially execute arbitrary code on the target system.

The __get_compat_argv() function is also affected.
Impact:   A local user may be able to obtain elevated privileges on the target system.
Solution:   Red Hat has issued a fix.

The Red Hat advisory is available at:

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

Synopsis:          Moderate: systemtap security update
Advisory ID:       RHSA-2010:0125-01
Product:           Red Hat Enterprise Linux
Advisory URL:      https://rhn.redhat.com/errata/RHSA-2010-0125.html
Issue date:        2010-03-01
CVE Names:         CVE-2010-0411 
=====================================================================

1. Summary:

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

This update has been rated as having moderate security impact by the Red
Hat Security Response Team.

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.

A buffer overflow flaw was found in SystemTap's tapset __get_argv()
function. If a privileged user ran a SystemTap script that called this
function, a local, unprivileged user could, while that script is still
running, trigger this flaw and cause memory corruption by running a command
with a large argument list, which may lead to a system crash or,
potentially, arbitrary code execution with root privileges. (CVE-2010-0411)

Note: SystemTap scripts that call __get_argv(), being a privileged
function, can only be executed by the root user or users in the stapdev
group. As well, if such a script was compiled and installed by root, users
in the stapusr group would also be able to execute it.

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 that all previously-released
errata relevant to your system have been applied.

This update is available via 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
