RHEL 5: RHSA-2012:0311-03 Low Severity: Ibutils Local Exploit

Calendar Grey February 21, 2012
Scroller Redhat
A recent update for Red Hat Enterprise Linux addresses a minor security flaw in ibutils that could affect local users. It's advised to apply this update for improved system security
Updated ibutils packages that fix one security issue and one bug are now available for Red Hat Enterprise Linux 5

Solution

Before applying this update, make sure all previously-released errata relevant to your system have been applied.

This update is available via the Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at https://access.redhat.com/kb/docs/DOC-11259

Summary

The ibutils packages provide InfiniBand network and path diagnostics.
It was found that the ibmssh executable had an insecure relative RPATH (runtime library search path) set in the ELF (Executable and Linking Format) header. A local user able to convince another user to run ibmssh in an attacker-controlled directory could run arbitrary code with the privileges of the victim. (CVE-2008-3277)
This update also fixes the following bug:
* Under certain circumstances, the "ibdiagnet -r" command could suffer from memory corruption and terminate with a "double free or corruption" message and a backtrace. With this update, the correct memory management function is used to prevent the corruption. (BZ#711779)
All users of ibutils are advised to upgrade to these updated packages, which contain backported patches to correct these issues.
