Overview
The Microsoft SNMP agent, prior to Windows NT 4.0 Service Pack 4.0, will leak memory.
Description
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. |
Impact
Intruders can consume memory on vulnerable machines, causing denial or degredation of service. |
Solution
Upgrade to Windows NT service pack 4 or later, as described in http://support.microsoft.com/support/kb/articles/q178/3/81.asp. |
