Descripción
*** Pendiente de traducción *** The GOOSE payload parser contains a boundary handling flaw that can be <br />
triggered by a single unauthenticated Layer 2 multicast frame on the <br />
process bus. When processing specific payload fields, an attacker <br />
controlled inner element length may exceed its enclosing length, causing<br />
the parser to over read by one byte. This out-of-bounds read reliably <br />
terminates the subscriber process, resulting in a denial-of-service <br />
condition.
