Description :

From Red Hat Security Advisory 2011:0842 :

Updated systemtap packages that fix two security issues are now
available for Red Hat Enterprise Linux 6.

The Red Hat Security Response Team has rated this update as having
moderate security impact. Common Vulnerability Scoring System (CVSS)
base scores, which give detailed severity ratings, are available for
each vulnerability from the CVE links in the References section.

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,

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