Atmel SNMP public Community or Unknown OID Denial of Service Vulnerability

Atmel is a chip design and manufacturing firm that provides various RF-based products to corporate consumers. Atmel manufactures firmware for various wireless access systems. The firmware supports the SNMP protocol for network management.

If a SNMP read request is sent with a community string other than 'public', or an unknown OID key, a denial of service condition is created. The device will not respond to further communication, and a restart is required to regain normal functionality.
