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 prior to ucd-snmp-utils-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. 4.
