RHSA-2009:1646 - Moderate: libtool security update

Synopsis

Moderate: libtool security update

Type/Severity

Security Advisory Moderate

Topic

Updated libtool packages that fix one security issue are now available for Red Hat Enterprise Linux 3, 4, and 5.

This update has been rated as having moderate security impact by the Red Hat Security Response Team.

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.

Solution

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