Synopsis:	Moderate: libtool security update
Issue date:	2009-12-08
CVE Names:	CVE-2009-3736

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

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)

After installing the updated packages, applications using the libltdl
library must be restarted for the update to take effect.
