For connection templates, however, they only log states outside\nthe template state range and still store the value in the connection.\n\nA template can be returned by ordinary connection lookup. TCP and SCTP then\nuse the invalid state as an index into their transition tables.\n\nReject invalid template states in both sync protocol versions before\nlooking up or modifying a connection. The version 1 path handles both\nIPv4 and IPv6 records.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"sunlit","depthScore":3,"depthScoreParts":{"impact":2.8,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
