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_at":"2020-01-21T00:00:00Z","last_modified_at":null,"cvss_v3_score":6.5,"cvss_v3_vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H","cvss_v3_severity":"MEDIUM","cvss_v4_score":null,"cvss_v4_vector":null,"cvss_v4_severity":null,"ssvc_decision":null,"ssvc_exploitation":null,"ssvc_automatable":null,"ssvc_technical_impact":null,"cwes":["CWE-125"],"nvd_references":["https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2019-14907","https://www.samba.org/samba/security/CVE-2019-14907.html","https://security.netapp.com/advisory/ntap-20200122-0001/","https://www.synology.com/security/advisory/Synology_SA_20_01","https://usn.ubuntu.com/4244-1/","http://lists.opensuse.org/opensuse-security-announce/2020-01/msg00055.html","https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/GQ6U65I2K23YJC4FESW477WL55TU3PPT/","https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/4ACZVNMIFQGGXNJPMHAVBN3H2U65FXQY/","https://security.gentoo.org/glsa/202003-52","https://lists.debian.org/debian-lts-announce/2021/05/msg00023.html","https://lists.debian.org/debian-lts-announce/2023/09/msg00013.html"],"vuln_status":null,"trending_score":null,"is_trending":false,"has_trended":false,"trended_number_one":false,"trending_peak_score":null,"trending_peak_rank":null,"started_trending_at":null,"trended_number_one_at":null,"summary_generated":null,"summary_generated_at":null,"summary_model":null,"created_at":"2026-06-24T00:09:39.878444Z","updated_at":"2026-06-28T23:12:12.571806Z"},"effective_severity":"MEDIUM","badges":[],"impact_analysis":[],"cvss_v3_decoded":{"version":"3.1","metrics":[{"metric":"AV","name":"Attack
