Title:RedHat Security Advisory RHSA-2011:0842
The remote host is missing updates announced in
advisory RHSA-2011:0842.

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.

Two divide-by-zero flaws were found in the way SystemTap handled malformed
debugging information in DWARF format. When SystemTap unprivileged mode was
enabled, an unprivileged user in the stapusr group could use these flaws to
crash the system. Additionally, a privileged user (root, or a member of the
stapdev group) could trigger these flaws when tricked into instrumenting a
specially-crafted ELF binary, even when unprivileged mode was not enabled.
(CVE-2011-1769, CVE-2011-1781)

SystemTap users should upgrade to these updated packages, which contain a
backported patch to correct these issues.

Please note that this update is available via
Red Hat Network. To use Red Hat Network, launch the Red
Hat Update Agent with the following command: up2date
