{"id":"CVE-2018-12228","details":"An issue was discovered in Asterisk Open Source 15.x before 15.4.1. 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.","modified":"2026-03-14T09:26:14.149982Z","published":"2018-06-12T04:29:00.330Z","references":[{"type":"ADVISORY","url":"http://downloads.asterisk.org/pub/security/AST-2018-007.html"},{"type":"ADVISORY","url":"http://www.securityfocus.com/bid/104457"},{"type":"EVIDENCE","url":"https://issues.asterisk.org/jira/browse/ASTERISK-27807"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/asterisk/asterisk","events":[{"introduced":"d4cc63728def7ca06ad3f70547de87bc5c9ef7c0"},{"fixed":"97b17a97812a5b3f30dba94cc7b3b3a2e81473e5"}],"database_specific":{"versions":[{"introduced":"15.0"},{"fixed":"15.4.1"}]}}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2018-12228.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"}]}
