Descripción
*** Pendiente de traducción *** An unauthenticated remote attacker can exhaust<br />
server memory via the FindServers Discovery Service in open62541. The<br />
serverUris field of FindServersRequest is not validated for length or array<br />
size. An attacker can declare an arbitrarily large string (up to ~3.9 GB)<br />
delivered across intermediate chunks without ever sending the final chunk. The<br />
server buffers all chunks in RAM indefinitely until the SecureChannel times<br />
out. The attack is pre-session and bypasses all encryption configuration. The issue affects open62541: from 1.4.0 through 1.4.16, from 1.5.0 through 1.5.4, master.
