Oracle Linux 5 / 6 : systemtap (ELSA-2010-0894)

High Nessus Plugin ID 68146


The remote Oracle Linux host is missing one or more security updates.


From Red Hat Security Advisory 2010:0894 :

Updated systemtap packages that fix two security issues are now available for Red Hat Enterprise Linux 5 and 6.

The Red Hat Security Response Team has rated this update as having important security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

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.


Update the affected systemtap packages.
