Scientific Linux Security Update : systemtap on SL5.x, SL6.x i386/x86_64 (20120308)

medium Nessus Plugin ID 61281

Language:

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.

Solution

Update the affected packages.
