Red Hat Security Advisory
Synopsis: Moderate: net-snmp security update
Advisory ID: RHSA-2009:0295-01
Product: Red Hat Enterprise Linux
Advisory URL: https://rhn.redhat.com/errata/RHSA-2009-0295.html
Issue date: 2009-03-26
CVE Names: CVE-2008-6123
=====================================================================
1. Summary:
Updated net-snmp packages that fix a security issue are now available for
Red Hat Enterprise Linux 3.
This update has been rated as having moderate security impact by the Red
Hat Security Response Team.
2. Relevant releases/architectures:
Red Hat Desktop version 3 - i386, x86_64
Red Hat Enterprise Linux AS version 3 - i386, ia64, ppc, s390, s390x, x86_64
Red Hat Enterprise Linux ES version 3 - i386, ia64, x86_64
Red Hat Enterprise Linux WS version 3 - i386, ia64, x86_64
3. Description:
The Simple Network Management Protocol (SNMP) is a protocol used for
network management.
It was discovered that the snmpd daemon did not use TCP wrappers correctly,
causing network hosts access restrictions defined in "/etc/hosts.allow" and
"/etc/hosts.deny" to not be honored. A remote attacker could use this flaw
to bypass intended access restrictions. (CVE-2008-6123)
This issue only affected configurations where hosts.allow and hosts.deny
were used to limit access to the SNMP server. To obtain information from
the server, the attacker would have to successfully authenticate, usually
by providing a correct community string.
All net-snmp users should upgrade to these updated packages, which contain
a backported patch to correct this issue. After installing the update, the
snmpd and snmptrapd daemons will be restarted automatically.
4. Solution:
Before applying this update, make sure that all previously-released
errata relevant to your system have been applied.
This update is available via Red Hat Network. Details on how to use
the Red Hat Network to apply this update are available at
http://kbase.redhat.com/faq/docs/DOC-11259
5. Bugs fixed (http://bugzilla.redhat.com/):
485211 - CVE-2008-6123 net-snmp: incorrect application of hosts access restrictions in hosts.{allow,deny}
