Ubuntu Security Notice USN-946-1
2nd June, 2010
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 10.04 LTS
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.
The problem can be corrected by updating your system to the following package version:
To update your system, please follow these instructions: https://wiki.ubuntu.com/Security/Upgrades.
In general, a standard system update will make all the necessary changes.
