| 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-2021-20208 | 3 Fedoraproject, Redhat, Samba | 3 Fedora, Enterprise Linux, Cifs-utils | 2024-11-21 | 6.1 Medium |
| A flaw was found in cifs-utils in versions before 6.13. A user when mounting a krb5 CIFS file system from within a container can use Kerberos credentials of the host. The highest threat from this vulnerability is to data confidentiality and integrity. | ||||
| 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-2020-1472 | 9 Canonical, Debian, Fedoraproject and 6 more | 20 Ubuntu Linux, Debian Linux, Fedora and 17 more | 2024-11-21 | 5.5 Medium |
| An elevation of privilege vulnerability exists when an attacker establishes a vulnerable Netlogon secure channel connection to a domain controller, using the Netlogon Remote Protocol (MS-NRPC). An attacker who successfully exploited the vulnerability could run a specially crafted application on a device on the network. To exploit the vulnerability, an unauthenticated attacker would be required to use MS-NRPC to connect to a domain controller to obtain domain administrator access. Microsoft is addressing the vulnerability in a phased two-part rollout. These updates address the vulnerability by modifying how Netlogon handles the usage of Netlogon secure channels. For guidelines on how to manage the changes required for this vulnerability and more information on the phased rollout, see How to manage the changes in Netlogon secure channel connections associated with CVE-2020-1472 (updated September 28, 2020). When the second phase of Windows updates become available in Q1 2021, customers will be notified via a revision to this security vulnerability. If you wish to be notified when these updates are released, we recommend that you register for the security notifications mailer to be alerted of content changes to this advisory. See Microsoft Technical Security Notifications. | ||||
| 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-2020-14387 | 1 Samba | 1 Rsync | 2024-11-21 | 7.4 High |
| A flaw was found in rsync in versions since 3.2.0pre1. Rsync improperly validates certificate with host mismatch vulnerability. A remote, unauthenticated attacker could exploit the flaw by performing a man-in-the-middle attack using a valid certificate for another hostname which could compromise confidentiality and integrity of data transmitted using rsync-ssl. The highest threat from this vulnerability is to data confidentiality and integrity. This flaw affects rsync versions before 3.2.4. | ||||
| 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-2020-14342 | 3 Fedoraproject, Opensuse, Samba | 3 Fedora, Leap, Cifs-utils | 2024-11-21 | 4.4 Medium |
| It was found that cifs-utils' mount.cifs was invoking a shell when requesting the Samba password, which could be used to inject arbitrary commands. An attacker able to invoke mount.cifs with special permission, such as via sudo rules, could use this flaw to escalate their privileges. | ||||
| 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. | ||||
