| CVE-2021-23192 | — | < 4.15.2+git.193.a4d6307f1fd-1.1 | 4.15.2+git.193.a4d6307f1fd-1.1 | Mar 2, 2022 | A flaw was found in the way samba implemented DCE/RPC. If a client to a Samba server sent a very large DCE/RPC request, and chose to fragment it, an attacker could replace later fragments with their own data, bypassing the signature requirements. | ||
| CVE-2021-44142 | — | < 4.15.5+git.328.f1f29505d84-1.1 | 4.15.5+git.328.f1f29505d84-1.1 | Feb 21, 2022 | The Samba vfs_fruit module uses extended file attributes (EA, xattr) to provide "...enhanced compatibility with Apple SMB clients and interoperability with a Netatalk 3 AFP fileserver."

| CVE-2020-25717 | — | < 4.15.2+git.193.a4d6307f1fd-1.1 | 4.15.2+git.193.a4d6307f1fd-1.1 | Feb 18, 2022 | A flaw was found in the way Samba maps domain users to local users. An authenticated attacker could use this flaw to cause possible privilege escalation. | ||
| CVE-2016-2124 | — | < 4.15.2+git.193.a4d6307f1fd-1.1 | 4.15.2+git.193.a4d6307f1fd-1.1 | Feb 18, 2022 | A flaw was found in the way samba implemented SMB1 authentication. An attacker could use this flaw to retrieve the plaintext password sent over the wire even if Kerberos authentication was required. | ||
| CVE-2020-27840 | — | < 4.14.6+git.182.2205d5224e3-1.1 | 4.14.6+git.182.2205d5224e3-1.1 | May 12, 2021 | A flaw was found in samba. Spaces used in a string around a domain name (DN), while supposed to be ignored, can cause invalid DN strings with spaces to instead write a zero-byte into out-of-bounds memory, resulting in a crash. The highest threat from this vulnerability is to syst | ||
| CVE-2021-20277 | — | < 4.14.6+git.182.2205d5224e3-1.1 | 4.14.6+git.182.2205d5224e3-1.1 | May 12, 2021 | A flaw was found in Samba's libldb. Multiple, consecutive leading spaces in an LDAP attribute can lead to an out-of-bounds memory write, leading to a crash of the LDAP server process handling the request. The highest threat from this vulnerability is to system availability. | ||
