| CVE-2018-16857 | Hig | 0.48 | 7.4 | 0.02 | Nov 28, 2018 | Samba from version 4.9.0 and before version 4.9.3 that have AD DC configurations watching for bad passwords (to restrict brute forcing of passwords) in a window of more than 3 minutes may not watch for bad passwords at all. The primary risk from this issue is with regards to… | ||
| CVE-2017-12151 | Hig | 0.48 | 7.4 | 0.05 | Jul 27, 2018 | A flaw was found in the way samba client before samba 4.4.16, samba 4.5.14 and samba 4.6.8 used encryption with the max protocol set as SMB3.

| CVE-2015-5252 | Hig | 0.48 | 7.2 | 0.13 | Dec 29, 2015 | vfs.c in smbd in Samba 3.x and 4.x before 4.1.22, 4.2.x before 4.2.7, and 4.3.x before 4.3.3, when share names with certain substring relationships exist, allows remote attackers to bypass intended file-access restrictions via a symlink that points outside of a share. | ||
| CVE-2020-25719 | Hig | 0.47 | 7.2 | 0.02 | Feb 18, 2022 | A flaw was found in the way Samba, as an Active Directory Domain Controller, implemented Kerberos name-based authentication.
