Such strings can be provided during the NTLMSSP authentication exchange. In the Samba AD DC in particular, this may cause a long-lived process(such as the RPC server) to terminate. (In the file server case, the most likely target, smbd, operates as process-per-client and so a crash there is harmless).","published":"2020-01-21T18:15:13.000Z","lastModified":"2026-06-17T02:19:18.000Z","status":"Modified","sourceIdentifier":"secalert@redhat.com","cvss":{"version":"3.1","score":6.5,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H"},"cwe":["CWE-125"],"affected":["samba/samba","fedoraproject/fedora","redhat/storage","redhat/enterprise linux","canonical/ubuntu linux","synology/directory server","synology/router manager","synology/skynas","synology/diskstation manager","debian/debian linux"],"epss":{"score":0.03151,"percentile":0.8788,"date":"2026-10-27","history":[]},"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 (3.15%).
