Red Hat Security Advisory
Synopsis: Moderate: net-snmp security update
Advisory ID: RHSA-2009:1124-01
Product: Red Hat Enterprise Linux
Advisory URL: https://rhn.redhat.com/errata/RHSA-2009-1124.html
Issue date: 2009-06-25
CVE Names: CVE-2009-1887
=====================================================================
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 Enterprise Linux AS version 3 - i386, ia64, ppc, s390, s390x, x86_64
Red Hat Desktop version 3 - i386, 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.
A divide-by-zero flaw was discovered in the snmpd daemon. A remote attacker
could issue a specially-crafted GETBULK request that could crash the snmpd
daemon. (CVE-2009-1887)
Note: An attacker must have read access to the SNMP server in order to
exploit this flaw. In the default configuration, the community name
"public" grants read-only access. In production deployments, it is
recommended to change this default community name.
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/):
506903 - CVE-2009-1887 net-snmp: DoS (division by zero) via SNMP GetBulk requests
