Security readout for executives and security teams

Scapy 2.4.0 can become stuck and unresponsive when it parses specially crafted RADIUS-related packet data. The data may arrive over the network or from a pcap file. Business risk is disruption to monitoring, packet analysis, security tooling, or automated workflows that rely on vulnerable Scapy parsing. Exposure is most likely where Scapy 2.4.0 is installed in packet capture, network inspection, lab tooling, parsers, CI jobs, or security automation that processes RADIUS traffic or untrusted pcaps. Treat this as a targeted operational resilience issue. Prioritize remediation where Scapy supports security monitoring, incident response, or automated packet processing, especially when it handles untrusted network traffic or pcaps. Mitigation focus: Inventory systems, containers, and tools using Scapy 2.4.0.; Upgrade Scapy or distribution packages according to Scapy and vendor guidance.; Avoid feeding untrusted pcaps to affected Scapy-based workflows..
