Description :

CVE-2009-4273 systemtap: remote code execution via stap-server

CVE-2010-0411 systemtap: Crash with systemtap script using

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. (CVE-2009-4273)

Note: stap-server is not run by default. It must be started by a user
or administrator.

A buffer overflow flaw was found in SystemTap's tapset __get_argv()
function. If a privileged user ran a SystemTap script that called this
function, a local, unprivileged user could, while that script is still
running, trigger this flaw and cause memory corruption by running a
command with a large argument list, which may lead to a system crash
or, potentially, arbitrary code execution with root privileges.

Note: SystemTap scripts that call __get_argv(), being a privileged
function, can only be executed by the root user or users in the
stapdev group. As well, if such a script was compiled and installed by
root, users in the stapusr group would also be able to execute it.
