CVE-2023-7242

Estado: ModificadaAlta (8.2)—

Industrial Control Systems Network Protocol Parsers (ICSNPP) - Ethercat Zeek Plugin versions d78dda6 and prior are vulnerable to out-of-bounds read during the process of analyzing a specific Ethercat packet. This could allow an attacker to crash the Zeek process and leak some information in memory.
