Synopsis: Important: systemtap security update Issue date: 2010-03-01 CVE Names: CVE-2009-4273 CVE-2010-0411 CVE-2009-4273 systemtap: remote code execution via stap-server CVE-2010-0411 systemtap: Crash with systemtap script using __get_argv() 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. (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.
