For those issues to happen, a malformed\nwire message is needed to be sent from the device.\n\nInstead of duplicating the bounds checking code already present in\ndecode_message(), use the function inside resp_worker().\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":[]}
