3. Description:

GNU Libtool is a set of shell scripts which automatically configure UNIX,
Linux, and similar operating systems to generically build shared libraries.

A flaw was found in the way GNU Libtool's libltdl library looked for
modules to load. It was possible for libltdl to load and run modules from
an arbitrary library in the current working directory. If a local attacker
could trick a local user into running an application (which uses libltdl)
from an attacker-controlled directory containing a malicious Libtool
control file (.la), the attacker could possibly execute arbitrary code with
the privileges of the user running the application. (CVE-2009-3736)

All libtool users should upgrade to these updated packages, which contain
a backported patch to correct this issue. After installing the updated
packages, applications using the libltdl library must be restarted for the
update to take effect.

4. Solution:

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

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

5. Bugs fixed (http://bugzilla.redhat.com/):

537941 - CVE-2009-3736 libtool: libltdl may load and execute code from a library in the current directory
