When connected to Asterisk via TCP/TLS, if the client abruptly disconnects, or sends a specially crafted message, then Asterisk gets caught in an infinite loop while trying to read the data stream. This renders the system unusable.","published":"2018-06-12T04:29:00.000Z","lastModified":"2026-06-17T01:37:23.000Z","status":"Modified","sourceIdentifier":"cve@mitre.org","cvss":{"version":"3.0","score":6.5,"severity":"MEDIUM","vector":"CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"},"cwe":["CWE-835"],"affected":["sangoma/asterisk"],"epss":{"score":0.06462,"percentile":0.93702,"date":"2026-10-27","history":[{"date":"2026-09-21","score":0.05644,"percentile":0.92662},{"date":"2026-09-22","score":0.06698,"percentile":0.93611}]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"low","text":"Lower severity and a low EPSS score (6.46%).
