Title: Net-SNMP snmpnetstat Remote Heap Overflow Vulnerability
Severity: HIGH
Description:
Net-SNMP is a package of software tools related to the Simple Network Management Protocol. One of the tools included is snmpnetstat, which can be used to retrieve and display a variety of information about a remote SNMP host.
A heap overflow vulnerability exists in the snmpnetstat client. A SNMP host may return malicious information when a list of interfaces is requested. Under some circumstances, this will result in a heap overflow in the SNMP client. Exploitation of this vulnerability can result in the execution of abritary code as the snmpnetstat client.
While the snmpnetstat client would normally execute as a non-privileged user, exploitation of this vulnerability could easily result in local access for the attacker. From a local standpoint, further elevation of privileges may be easier to obtain.
Earlier versions of Net-SNMP may also be vulnerable.
