systemtap is vulnerable to arbitrary code execution. The vulnerability exists as a flaw was found in the SystemTap compile server, stap-server, an optional component of SystemTap. This server did not adequately sanitize input provided by the stap-client program, which may allow a remote user to execute arbitrary shell code with the privileges of the compile server process, which could possibly be running as the root user.
