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)

Note: On Scientific Linux 4, an attacker must be a member of the
stapusr group to exploit this issue. Also note that, 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"
