Red Hat Security Advisory

 

Synopsis: Important: systemtap security update

Advisory ID: RHSA-2010:0124-01

Product: Red Hat Enterprise Linux

Advisory URL: https://rhn.redhat.com/errata/RHSA-2010-0124.html

Issue date: 2010-03-01

CVE Names: CVE-2009-4273 CVE-2010-0411

=====================================================================

 

1. Summary:

 

Updated systemtap packages that fix two security issues are now available

for Red Hat Enterprise Linux 5.

 

This update has been rated as having important security impact by the Red

Hat Security Response Team.

 

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, version 2.6. Developers can write scripts to collect data on the

operation of the system.

 

A flaw was found in the SystemTap compile server, stap-server, an optional

component of SystemTap. This server did not adequately sanitize input

provided by the stap-client program, which may allow a remote user to

execute arbitrary shell code with the privileges of the compile server

process, which could possibly be running as the root user. (CVE-2009-4273)

 

Note: stap-server is not run by default. It must be started by a user or

administrator.

 

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

backported patches to correct these issues.

 

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

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

 

550172 - CVE-2009-4273 systemtap: remote code execution via stap-server
