| CVE-2021-3738 | 1 Samba | 1 Samba | 2024-11-21 | 8.8 High |
| In DCE/RPC it is possible to share the handles (cookies for resource state) between multiple connections via a mechanism called 'association groups'. These handles can reference connections to our sam.ldb database. However while the database was correctly shared, the user credentials state was only pointed at, and when one connection within that association group ended, the database would be left pointing at an invalid 'struct session_info'. The most likely outcome here is a crash, but it is possible that the use-after-free could instead allow different user state to be pointed at and this might allow more privileged access. | ||||
| CVE-2021-3671 | 3 Debian, Netapp, Samba | 5 Debian Linux, Management Services For Element Software, Management Services For Netapp Hci and 2 more | 2024-11-21 | 6.5 Medium |
| A null pointer de-reference was found in the way samba kerberos server handled missing sname in TGS-REQ (Ticket Granting Server - Request). An authenticated user could use this flaw to crash the samba server. | ||||
| CVE-2021-23192 | 2 Redhat, Samba | 4 Enterprise Linux, Rhel Eus, Storage and 1 more | 2024-11-21 | 7.5 High |
| 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-2021-20316 | 3 Debian, Redhat, Samba | 8 Debian Linux, Enterprise Linux, Enterprise Linux Aus and 5 more | 2024-11-21 | 6.8 Medium |
| A flaw was found in the way Samba handled file/directory metadata. This flaw allows an authenticated attacker with permissions to read or modify share metadata, to perform this operation outside of the share. | ||||
| CVE-2021-20277 | 4 Debian, Fedoraproject, Redhat and 1 more | 8 Debian Linux, Fedora, Enterprise Linux and 5 more | 2024-11-21 | 7.5 High |
| 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. | ||||
| CVE-2021-20254 | 4 Debian, Fedoraproject, Redhat and 1 more | 9 Debian Linux, Fedora, Enterprise Linux and 6 more | 2024-11-21 | 6.8 Medium |
| A flaw was found in samba. The Samba smbd file server must map Windows group identities (SIDs) into unix group ids (gids). The code that performs this had a flaw that could allow it to read data beyond the end of the array in the case where a negative cache entry had been added to the mapping cache. This could cause the calling code to return those values into the process token that stores the group membership for a user. The highest threat from this vulnerability is to data confidentiality and integrity. | ||||
| CVE-2021-20251 | 2 Fedoraproject, Samba | 2 Fedora, Samba | 2024-11-21 | 5.9 Medium |
| A flaw was found in samba. A race condition in the password lockout code may lead to the risk of brute force attacks being successful if special conditions are met. | ||||
| CVE-2020-27840 | 3 Debian, Fedoraproject, Samba | 3 Debian Linux, Fedora, Samba | 2024-11-21 | 7.5 High |
| 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 system availability. | ||||
| CVE-2020-25722 | 4 Canonical, Debian, Fedoraproject and 1 more | 4 Ubuntu Linux, Debian Linux, Fedora and 1 more | 2024-11-21 | 8.8 High |
| Multiple flaws were found in the way samba AD DC implemented access and conformance checking of stored data. An attacker could use this flaw to cause total domain compromise. | ||||
| CVE-2020-25721 | 1 Samba | 1 Samba | 2024-11-21 | 8.8 High |
| Kerberos acceptors need easy access to stable AD identifiers (eg objectSid). Samba as an AD DC now provides a way for Linux applications to obtain a reliable SID (and samAccountName) in issued tickets. | ||||
| CVE-2020-25719 | 5 Canonical, Debian, Fedoraproject and 2 more | 18 Ubuntu Linux, Debian Linux, Fedora and 15 more | 2024-11-21 | 7.2 High |
| A flaw was found in the way Samba, as an Active Directory Domain Controller, implemented Kerberos name-based authentication. The Samba AD DC, could become confused about the user a ticket represents if it did not strictly require a Kerberos PAC and always use the SIDs found within. The result could include total domain compromise. | ||||
| CVE-2020-25718 | 2 Fedoraproject, Samba | 2 Fedora, Samba | 2024-11-21 | 8.8 High |
| A flaw was found in the way samba, as an Active Directory Domain Controller, is able to support an RODC (read-only domain controller). This would allow an RODC to print administrator tickets. | ||||
| CVE-2020-25717 | 5 Canonical, Debian, Fedoraproject and 2 more | 28 Ubuntu Linux, Debian Linux, Fedora and 25 more | 2024-11-21 | 8.1 High |
| 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-2020-17049 | 3 Microsoft, Redhat, Samba | 13 Windows Server 1903, Windows Server 1909, Windows Server 2004 and 10 more | 2024-11-21 | 6.6 Medium |
| A security feature bypass vulnerability exists in the way Key Distribution Center (KDC) determines if a service ticket can be used for delegation via Kerberos Constrained Delegation (KCD). To exploit the vulnerability, a compromised service that is configured to use KCD could tamper with a service ticket that is not valid for delegation to force the KDC to accept it. The update addresses this vulnerability by changing how the KDC validates service tickets used with KCD. | ||||
| CVE-2020-14383 | 2 Redhat, Samba | 2 Enterprise Linux, Samba | 2024-11-21 | 6.5 Medium |
| A flaw was found in samba's DNS server. An authenticated user could use this flaw to the RPC server to crash. This RPC server, which also serves protocols other than dnsserver, will be restarted after a short delay, but it is easy for an authenticated non administrative attacker to crash it again as soon as it returns. The Samba DNS server itself will continue to operate, but many RPC services will not. | ||||
| CVE-2020-14323 | 5 Debian, Fedoraproject, Opensuse and 2 more | 6 Debian Linux, Fedora, Leap and 3 more | 2024-11-21 | 5.5 Medium |
| A null pointer dereference flaw was found in samba's Winbind service in versions before 4.11.15, before 4.12.9 and before 4.13.1. A local user could use this flaw to crash the winbind service causing denial of service. | ||||
| CVE-2020-14318 | 2 Redhat, Samba | 3 Enterprise Linux, Storage, Samba | 2024-11-21 | 4.3 Medium |
| A flaw was found in the way samba handled file and directory permissions. An authenticated user could use this flaw to gain access to certain file and directory information which otherwise would be unavailable to the attacker. | ||||
| CVE-2020-14303 | 5 Canonical, Debian, Fedoraproject and 2 more | 5 Ubuntu Linux, Debian Linux, Fedora and 2 more | 2024-11-21 | 7.5 High |
| A flaw was found in the AD DC NBT server in all Samba versions before 4.10.17, before 4.11.11 and before 4.12.4. A samba user could send an empty UDP packet to cause the samba server to crash. | ||||
| CVE-2020-10760 | 4 Canonical, Fedoraproject, Opensuse and 1 more | 4 Ubuntu Linux, Fedora, Leap and 1 more | 2024-11-21 | 6.5 Medium |
| A use-after-free flaw was found in all samba LDAP server versions before 4.10.17, before 4.11.11, before 4.12.4 used in a AC DC configuration. A Samba LDAP user could use this flaw to crash samba. | ||||
| CVE-2020-10745 | 4 Debian, Fedoraproject, Opensuse and 1 more | 4 Debian Linux, Fedora, Leap and 1 more | 2024-11-21 | 7.5 High |
| A flaw was found in all Samba versions before 4.10.17, before 4.11.11 and before 4.12.4 in the way it processed NetBios over TCP/IP. This flaw allows a remote attacker could to cause the Samba server to consume excessive CPU use, resulting in a denial of service. This highest threat from this vulnerability is to system availability. | ||||
