                   Red Hat, Inc. Red Hat Security Advisory

Synopsis:          Updated Net-SNMP packages fix security and other bugs
Advisory ID:       RHSA-2002:228-11
Issue date:        2002-10-09
Updated on:        2002-12-17
Product:           Red Hat Linux

CVE Names:         CAN-2002-1170
- ---------------------------------------------------------------------

1. Topic:

The Net-SNMP packages shipped with Red Hat Linux 8.0 contain several bugs
including a remote denial of service vulnerability. This errata release
corrects those problems.

2. Relevant releases/architectures:

Red Hat Linux 8.0 - i386

3. Problem description:

The Net-SNMP project includes various Simple Network Management Protocol
(SNMP) tools.

The SNMP daemon included in the Net-SNMP package versions 5.0.1 through
5.0.4 can be caused to crash if it is sent a specially crafted packet.
Successful exploitation of this issue would require knowledge of a known
SNMP community string.

Red Hat Linux 8.0 shipped with Net-SNMP 5.0.1 and is therefore vulnerable
to this issue.  Users of Net-SNMP should upgrade to these errata packages
containing Net-SNMP 5.0.6 which is not vulnerable to this issue.  In
addition, Net-SNMP 5.0.6 fixes a number of other minor bugs.

4. Solution:

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

To update all RPMs for your particular architecture, run:

rpm -Fvh [filenames]

where [filenames] is a list of the RPMs you wish to upgrade.  Only those
RPMs which are currently installed will be updated.  Those RPMs which are
not installed but included in the list will not be updated.  Note that you
can also use wildcards (*.rpm) if your current directory *only* contains the
desired RPMs.

Please note that this update is also available via Red Hat Network.  Many
people find this an easier way to apply updates.  To use Red Hat Network,
launch the Red Hat Update Agent with the following command:

up2date

This will start an interactive process that will result in the appropriate
RPMs being upgraded on your system.

5. Bug IDs fixed (http://bugzilla.redhat.com/bugzilla for more info):

75433 - Milan 8.0 net-snmp daemon dies when stressing it with gets and getnexts
78960 - Remote Denial of Service with Net-SNMP

6. RPMs required:

Red Hat Linux 8.0:

These packages are GPG signed by Red Hat, Inc. for security.  Our key
is available at http://www.redhat.com/about/contact/pgpkey.html

You can verify each package with the following command:
    
    rpm --checksig -v <filename>

If you only wish to verify that each package has not been corrupted or
tampered with, examine only the md5sum with the following command:
    
    md5sum <filename>
