                Bugs fixed in pump (DHCP client) [CORRECTION]
                               18 August 1999

===========================================================================

Red Hat Software, Inc. has released the following advisory concerning a
new version of pump, 0.7.0, addressing several problems, including a
potential security vulnerability which may allow remote users to gain root
access.

		   Red Hat, Inc. Security Advisory

Synopsis:		Bugs fixed in pump (DHCP client) [CORRECTION]
Advisory ID:		RHSA-1999:027-02
Issue date:		1999-08-11
Updated on:		1999-08-14
Keywords:		pump DHCP RoadRunner @Home
Cross references:	
- ---------------------------------------------------------------------

1. Topic:

New version of pump, 0.7.0, fixes several problems, including a
potential security hole.  We strongly recommend that all users
using DHCP upgrade to pump 0.7.0, particularly if you use DHCP
on a public network such as a cable modem or ADSL service.

This is a correction to our previous announcement, which did not
mention the security bug that is fixed in pump 0.7.0.

2. Bug IDs fixed:

3263

3. Relevant releases/architectures:

Red Hat Linux 6.0, all architectures.

4. Obsoleted by:

5. Conflicts with:

6. RPMs required:

Intel:
  ftp://ftp.redhat.com/redhat/updates/6.0/i386/pump-0.7.0-1.i386.rpm

Alpha:
  ftp://ftp.redhat.com/redhat/updates/6.0/alpha/pump-0.7.0-1.alpha.rpm

Sparc:
  ftp://ftp.redhat.com/redhat/updates/6.0/sparc/pump-0.7.0-1.sparc.rpm

Source packages:
  ftp://ftp.redhat.com/redhat/updates/6.0/SRPMS/pump-0.7.0-1.src.rpm


7. Problem description:

 o  DHCP did not work with some @Home and RoadRunner (and potentially
    other) servers.

 o  Some (broken) servers did not return server address properly; in these
    cases, pump now reuses the broadcast address.

 o  There was a security hole with the potential for a remote root
    exploit in certain configurations where DHCP is used on public
    networks

8. Solution:

For each RPM for your particular architecture, run:
 
rpm -Uvh <filename>
 
where filename is the name of the RPM.

9. Verification:

MD5 sum                           Package Name
