The remote Red Hat host is missing one or more security updates.
Updated systemtap packages that fix a security issue are now available
for Red Hat Enterprise Linux 4.
This update has been rated as having moderate security impact by the
Red Hat Security Response Team.
SystemTap is an instrumentation system for systems running the Linux
kernel, version 2.6. Developers can write scripts to collect data on
the operation of the system.
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.
SystemTap users should upgrade to these updated packages, which
contain a backported patch to correct this issue.
