| CVE-2017-11103 | Hig | 0.53 | 8.1 | 0.05 | Jul 13, 2017 | Heimdal before 7.4 allows remote attackers to impersonate services with Orpheus' Lyre attacks because it obtains service-principal names in a way that violates the Kerberos 5 protocol specification. In _krb5_extract_ticket() the KDC-REP service name must be obtained from the… | ||
| CVE-2026-4408 | Cri | 0.52 | 9.0 | 0.03 | May 28, 2026 | A flaw was found in Samba. A remote attacker can exploit a misconfiguration in Samba file servers and classic domain controllers that use the "check password script" feature. If this script is configured with the %u substitution character, the client-controlled username is… | ||
| CVE-2016-2123 | Hig | 0.51 | 8.8 | 0.06 | Nov 1, 2018 | A flaw was found in samba versions 4.0.0 to 4.5.2. The Samba routine ndr_pull_dnsp_name contains an integer wrap problem, leading to an attacker-controlled memory overwrite. ndr_pull_dnsp_name parses data from the Samba Active Directory ldb database. Any user who can write to… | ||
| CVE-2017-15275 | Hig | 0.50 | 7.5 | 0.21 | Nov 27, 2017 | Samba before 4.7.3 might allow remote attackers to obtain sensitive information by leveraging failure of the server to clear allocated heap memory. | ||
