The remote Red Hat host is missing one or more security updates.
Updated systemtap packages that fix one security issue are now
available for Red Hat Enterprise Linux 5.
The Red Hat Security Response Team has rated this update as having
moderate security impact. A Common Vulnerability Scoring System (CVSS)
base score, which gives a detailed severity rating, is available from
the CVE link 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.
A divide-by-zero flaw was 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
this flaw to crash the system. Additionally, a privileged user (root,
or a member of the stapdev group) could trigger this flaw 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 this issue.
