Arbitrary Code Execution

systemtap is vulnerable to arbitrary code execution. The vulnerability exists as it was found that SystemTap did not perform proper module path sanity checking if a user specified a custom path to the uprobes module, used when performing user-space probing (“staprun -u”). A local user who is a member of the stapusr group could use this flaw to bypass intended module-loading restrictions, allowing them to escalate their privileges by loading an arbitrary, unsigned module.
