In a typical installation, the telnetd application would crash but the telnet service would remain available through inetd. However, if the telnetd application has many crashes within a short time interval, the telnet service would become unavailable after inetd logs a \"telnet/tcp server failing (looping), service terminated\" error. NOTE: MIT krb5-appl is not supported upstream but is shipped by a few Linux distributions. The affected code was removed from the supported MIT Kerberos 5 (aka krb5) product many years ago, at version 1.8.\n\n\ud83d\udcd6 Read\n\nvia \"National Vulnerability Database\".", "creation_timestamp": "2022-08-30T12:35:19.000000Z"}, {"uuid": "2f5d4a0d-f021-44aa-b5c3-3aa0e02e7c01", "vulnerability_lookup_origin": "1a89b78e-f703-45f3-bb86-59eb712668bd", "author": "4f29edb9-4c4b-44ca-b041-9b050656b6ae", "vulnerability": "CVE-2022-39028", "type": "seen", "source": "https://t.me/reverseame/2673", "content": "", "creation_timestamp": "2026-07-29T12:02:38.807591Z"}, {"uuid": "70c55b43-b308-421c-8eac-a2aa26368ec2", "vulnerability_lookup_origin": "1a89b78e-f703-45f3-bb86-59eb712668bd", "author": "4f29edb9-4c4b-44ca-b041-9b050656b6ae", "vulnerability": "CVE-2022-39028", "type": "seen", "source": "https://t.me/reverseame/2673", "content": "", "creation_timestamp": "2026-07-30T00:02:35.185477Z"}, {"uuid": "0f8e04cd-579e-4057-a640-f9e8b07f652e", "vulnerability_lookup_origin": "1a89b78e-f703-45f3-bb86-59eb712668bd", "author": "4f29edb9-4c4b-44ca-b041-9b050656b6ae", "vulnerability": "CVE-2022-39028", "type": "published-proof-of-concept", "source": "https://t.me/reverseame/2673", "content": "", "creation_timestamp": "2026-08-02T23:20:27.699474Z"}, {"uuid": "a3fc4f0e-a94d-4c2e-adf7-dca05c788b2c", "vulnerability_lookup_origin": "1a89b78e-f703-45f3-bb86-59eb712668bd", "author": "4f29edb9-4c4b-44ca-b041-9b050656b6ae", "vulnerability": "CVE-2022-39028", "type": "published-proof-of-concept", "source": "https://t.me/reverseame/2673", "content": "", "creation_timestamp": "2026-08-03T00:31:19.583910Z"}]}
