Vulnerability Note VU#4923
Windows NT SNMP agent leaks memory
The Microsoft SNMP agent, prior to Windows NT 4.0 Service Pack 4.0, will leak memory.
Microsoft's SNMP agent, snmp.exe, priot to Windows NT 4.0 Service Pack 4.0, will leak memory if the OID cannot be decoded. Quoting from Microsoft KB article Q178381,
If SNMP cannot decode an OID from a network packet, SNMP does not free up the memory, resulting in a memory leak in the Snmp.exe processes. The impact of this leak will be more evident on a system running on a network segment that receive lots of SNMP broadcast traffic.
This problem was addressed by Microsoft in Windows NT 4.0 Service Pack 4.0 and Windows NT Server 4.0, Terminal Server Edition Service Pack 4.
Intruders can consume memory on vulnerable machines, causing denial or degredation of service.
Upgrade to Windows NT service pack 4 or later, as described in http://support.microsoft.com/support/kb/articles/q178/3/81.asp.
