                   Red Hat Security Advisory

Synopsis:          Updated Net-SNMP packages fix security and other bugs
Advisory ID:       RHSA-2004:023-01
Issue date:        2004-01-15
Updated on:        0000-04-01
Product:           Red Hat Enterprise Linux
Keywords:          ucd-snmp
Cross references:  
Obsoletes:         
CVE Names:         CAN-2003-0935
- ---------------------------------------------------------------------

1. Topic:

Updated Net-SNMP packages are available to correct a security vulnerability
and other bugs.

2. Relevant releases/architectures:

Red Hat Enterprise Linux AS version 3 - i386, ia64, ppc, s390, s390x, x86_64
Red Hat Enterprise Linux ES version 3 - i386
Red Hat Enterprise Linux WS version 3 - i386, ia64, x86_64

3. Problem description:

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

A security issue in Net-SNMP versions before 5.0.9 could allow an existing
user/community to gain access to data in MIB objects that were explicitly
excluded from their view.  The Common Vulnerabilities and Exposures project
(cve.mitre.org) has assigned the name CAN-2003-0935 to this issue.

Users of Net-SNMP are advised to upgrade to these errata packages containing
Net-SNMP 5.0.9 which is not vulnerable to this issue.  In addition,
Net-SNMP 5.0.9 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):

109622 - net-snmp unauthorised access to mibs
