Title
lwIP 2.0.0 through 2.2.1 SNMP Agent Out-of-Bounds Read via snmp_pbuf_stream_writeto()
Summary
lwIP 2.0.0 through 2.2.1 built with the SNMP agent contains an out-of-bounds read vulnerability in snmp_pbuf_stream_writeto() that bounds copies by pbuf->len instead of remaining bytes. Remote unauthenticated attackers knowing the read community can send fragmented SNMP requests to receive adjacent receive-buffer or pool memory echoed in responses.
