Synopsis:	Important: systemtap security update
Issue date:	2010-11-17
CVE Names:	CVE-2010-4170 CVE-2010-4171

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.
