Scientific Linux Security Update : systemtap on SL4.x i386/x86_64
Medium Nessus Plugin ID 60741
SynopsisThe remote Scientific Linux host is missing one or more security updates.
DescriptionCVE-2010-0411 systemtap: Crash with systemtap script using
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.
SolutionUpdate the affected systemtap, systemtap-runtime and / or systemtap-testsuite packages.
