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": "9f56dd64-161d-43a6-b9c3-555944290a09", "vulnerability": "CVE-2022-39028", "type": "seen", "source": "https://t.me/reverseame/2673", "content": "2-byte DoS in freebsd-telnetd / netbsd-telnetd / netkit-telnetd / inetutils-telnetd / telnetd in Kerberos Version 5 Applications - Binary Golf Grand Prix 3 - CVE-2022-39028 https://pierrekim.github.io/blog/2022-08-24-2-byte-dos-freebsd-netbsd-telnetd-netkit-telnetd-inetutils-telnetd-kerberos-telnetd.html", "creation_timestamp": "2026-07-29T12:02:38.807591Z"}, {"uuid": "70c55b43-b308-421c-8eac-a2aa26368ec2", "vulnerability_lookup_origin": "1a89b78e-f703-45f3-bb86-59eb712668bd", "author": "9f56dd64-161d-43a6-b9c3-555944290a09", "vulnerability": "CVE-2022-39028", "type": "seen", "source": "https://t.me/reverseame/2673", "content": "2-byte DoS in freebsd-telnetd / netbsd-telnetd / netkit-telnetd / inetutils-telnetd / telnetd in Kerberos Version 5 Applications - Binary Golf Grand Prix 3 - CVE-2022-39028 https://pierrekim.github.io/blog/2022-08-24-2-byte-dos-freebsd-netbsd-telnetd-netkit-telnetd-inetutils-telnetd-kerberos-telnetd.html", "creation_timestamp": "2026-07-30T00:02:35.185477Z"}]}
