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

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:

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.

1. Summary:
Updated systemtap packages that fix one security issue are now available

security impact. A Common Vulnerability Scoring System (CVSS) base score,
which gives a detailed severity rating, is available from the CVE link in

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 divide-by-zero flaw was found in the way SystemTap handled malformed
debugging information in DWARF format. When SystemTap unprivileged mode was
enabled, an unprivileged user in the stapusr group could use this flaw to
crash the system. Additionally, a privileged user (root, or a member of the
stapdev group) could trigger this flaw when tricked into instrumenting a
specially-crafted ELF binary, even when unprivileged mode was not enabled.

backported patch to correct this issue.

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.
