USN-946-1: Net-SNMP vulnerability

2 June 2010

UDP clients might be able to bypass access restrictions of the SNMP server.



  • net-snmp - Simple Network Management Protocol server and libraries


The SNMP server did not correctly validate certain UDP clients when using
TCP wrappers. Under some situations, a remote attacker could bypass
access restrictions and communicate with the SNMP server, potentially
leading to a loss of privacy or a denial of service.

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 10.04

In general, a standard system update will make all the necessary changes.
