Oracle Linux 3 : net-snmp (ELSA-2009-1124)
Medium Nessus Plugin ID 67880
SynopsisThe remote Oracle Linux host is missing one or more security updates.
DescriptionFrom Red Hat Security Advisory 2009:1124 :
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.
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.
SolutionUpdate the affected net-snmp packages.
