Subject: OpenLinux: ucd-snmp remote heap overflow
Advisory number: CSSA-2003-029.0
Issue date: 2003 October 30

1. Problem Description
ucd-snmp is a set of tools relating to the Simple Network
Management Protocol (SNMP), which is used for remote
administration and monitoring of network devices and
services. Juan M. de la Torre found a remote heap overflow
vulnerability in snmpnetstat (a tool used to retrieve information
about a remote host). When a list of interfaces is requested, a
malicious server can return information in a way that will cause
a heap overflow in snmpnetstat. A remote atacker able to control
a snmp server can exploit this vulnerability to execute arbitrary
code with the privileges of the user running snmpnetstat.
2. Vulnerable Supported Versions
System Package
----------------------------------------------------------------------
OpenLinux 3.1.1 Server prior to ucd-snmp-4.2.1-18.i386.rpm
prior to
ucd-snmp-devel-4.2.1-18.i386.rpm
prior to
ucd-snmp-tkmib-4.2.1-18.i386.rpm
prior to
ucd-snmp-utils-4.2.1-18.i386.rpm
OpenLinux 3.1.1 Workstation prior to
ucd-snmp-4.2.1-18.i386.rpm
prior to
ucd-snmp-devel-4.2.1-18.i386.rpm
prior to
ucd-snmp-tkmib-4.2.1-18.i386.rpm

3. Solution
The proper solution is to install the latest packages. Many
customers find it easier to use the Caldera System Updater, called
cupdate (or kcupdate under the KDE environment), to update these
packages rather than downloading and installing them by hand.
