CVE-2010-0411 systemtap: Crash with systemtap script using __get_argv()

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. (CVE-2010-0411)

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.
