RHSA-2011:1088 - Moderate: systemtap security update
Synopsis
Moderate: systemtap security update
Type/Severity
Security Advisory Moderate
Topic
Updated systemtap packages that fix two security issues are now available for Red Hat Enterprise Linux 6.
The Red Hat Security Response Team has rated this update as having moderate 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.
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.
Solution
Before applying this update, make sure all previously-released errata relevant to your system have been applied.
