RHEL 3 / 4 / 5 : gcc and gcc4 (RHSA-2010:0039)

medium Nessus Plugin ID 43882

Language:

Synopsis

The remote Red Hat host is missing one or more security updates.

Description

Updated gcc and gcc4 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.

The gcc and gcc4 packages include, among others, C, C++, and Java GNU compilers and related support libraries. libgcj contains a copy of GNU Libtool's libltdl library.

A flaw was found in the way GNU Libtool's libltdl library looked for libraries to load. It was possible for libltdl to load a malicious library from the current working directory. In certain configurations, if a local attacker is able to trick a local user into running a Java application (which uses a function to load native libraries, such as System.loadLibrary) from within an attacker-controlled directory containing a malicious library or module, the attacker could possibly execute arbitrary code with the privileges of the user running the Java application. (CVE-2009-3736)

All gcc and gcc4 users should upgrade to these updated packages, which contain a backported patch to correct this issue. All running Java applications using libgcj must be restarted for this update to take effect.

Solution

Update the affected packages.
