RHBA-2013:1424 - Bug Fix Advisory

Topic

An updated net-tools package that fixes multiple bugs is now available for Red
Hat Enterprise Linux 5.

Description

The net-tools package contains basic networking tools, including ifconfig,
netstat, or route. Netstat, for example, prints information about the Linux
networking subsystem.

This update fixes the following bugs:

• When the "netstat --sctp -n" command was run on a system with large number of

Stream Control Transmission Protocol (SCTP) connections, the netstat utility
terminated unexpectedly with a segmentation fault. A patch that makes netstat
sanitize input has been applied and netstat no longer crashes. (BZ#1015547)

• Running the "netstat --sctp -n" command caused netstat to print IP addresses

incorrectly for the SCTP protocol. A patch has been back-ported from Red Hat
Enterprise Linux 6 and netstat now shows correct IP addresses for SCTP protocol.
(BZ#1015550)

All users of net-tools are advised to upgrade to this updated package, which
fixes these bugs.

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
