Cybersecurity Infrastructure and Security Agency (CISA) is warning of yet another TCP/IP stack vulnerability problem. Vulnerabilities could lead to remote code execution and denial-of-service attacks. No known exploits specifically target these vulnerabilities. Attackers would need a high skill level even to begin exploiting them, CISA says. The main method of mitigation would be to get the latest patches and apply them. CISA recommends that organizations implement firewall rules to filter out packets containing a negative content-length in the HTTP header.”]
