advisory RHSA-2009:0373.

SystemTap is an instrumentation infrastructure for systems running version
2.6 of the Linux kernel. SystemTap scripts can collect system operations
data, greatly simplifying information gathering. Collected data can then
assist in performance measuring, functional testing, and performance and
function problem diagnosis.

A race condition was discovered in SystemTap that could allow users in the
stapusr group to elevate privileges to that of members of the stapdev group

them to insert arbitrary SystemTap kernel modules. (CVE-2009-0784)

Note: This issue was only exploitable if another SystemTap kernel module
was placed in the systemtap/ module directory for the currently running

Red Hat would like to thank Erik Sjölund for reporting this issue.

SystemTap users should upgrade to these updated packages, which contain a
backported patch to correct this issue.

Red Hat Network. To use Red Hat Network, launch the Red
