Oracle Linux 6 : systemtap (ELSA-2011-0842)

low Nessus Plugin ID 68282

Synopsis

The remote Oracle Linux host is missing one or more security updates.

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, CVE-2011-1781)

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

Solution

Update the affected systemtap packages.
