NVD Description

Note: Versions mentioned in the description apply only to the upstream systemtap package and not the systemtap package as distributed by RHEL. See How to fix? for RHEL:6 relevant fixed versions and status.

The staprun runtime tool in SystemTap 1.3 does not verify that a module to unload was previously loaded by SystemTap, which allows local users to cause a denial of service (unloading of arbitrary kernel modules).
