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 http://kbase.redhat.com/faq/docs/DOC-11259
5. Bugs fixed (http://bugzilla.redhat.com/):
653604 - CVE-2010-4170 Systemtap: Insecure loading of modules 653606 - CVE-2010-4171 Systemtap: Ability to remove unused modules by unprivileged user
