NVD Description

Note: Versions mentioned in the description apply only to the upstream lwip package and not the lwip package as distributed by Echo. See How to fix? for Echo:latest relevant fixed versions and status.

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.
