Scientific Linux Security Update : systemtap on SL5.x, SL6.x i386/x86_64

This script is Copyright (C) 2012-2014 Tenable Network Security, Inc.


Synopsis :

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

Description :

SystemTap is an instrumentation system for systems running the Linux
kernel. The system allows developers to write scripts to collect data
on the operation of the system.

An invalid pointer read 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 or, potentially, read
arbitrary kernel memory. 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-2012-0875)

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