Scientific Linux Security Update : systemtap on SL5.x i386/x86_64
High Nessus Plugin ID 60904
SynopsisThe remote Scientific Linux host is missing one or more security updates.
DescriptionIt 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.
