In order to exploit this vulnerability, an attacker would have to have the ability to send arbitrary messages on the network. The only known exploit of this vulnerability leaks a limited number of bytes from the stack. No denial-of-service, memory corruption, or remote code execution has been shown.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"sunlit","depthScore":29,"depthScoreParts":{"impact":29.2,"likelihood":0.1,"exploitation":0,"ransomware":0},"changes":[]}
