CVE-2022-0336 2 Fedoraproject, Samba 2 Fedora, Samba 2024-11-21 8.8 High
The Samba AD DC includes checks when adding service principals names (SPNs) to an account to ensure that SPNs do not alias with those already in the database. Some of these checks are able to be bypassed if an account modification re-adds an SPN that was previously present on that account, such as one added when a computer is joined to a domain. An attacker who has the ability to write to an account can exploit this to perform a denial-of-service attack by adding an SPN that matches an existing service. Additionally, an attacker who can intercept traffic can impersonate existing services, resulting in a loss of confidentiality and integrity.
CVE-2021-44142 6 Canonical, Debian, Fedoraproject and 3 more 28 Ubuntu Linux, Debian Linux, Fedora and 25 more 2024-11-21 8.8 High
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." Samba versions prior to 4.13.17, 4.14.12 and 4.15.5 with vfs_fruit configured allow out-of-bounds heap read and write via specially crafted extended file attributes. A remote attacker with write access to extended file attributes can execute arbitrary code with the privileges of smbd, typically root.
CVE-2021-44141 3 Fedoraproject, Redhat, Samba 4 Fedora, Enterprise Linux, Storage and 1 more 2024-11-21 4.3 Medium
All versions of Samba prior to 4.15.5 are vulnerable to a malicious client using a server symlink to determine if a file or directory exists in an area of the server file system not exported under the share definition. SMB1 with unix extensions has to be enabled in order for this attack to succeed.
CVE-2021-43566 2 Redhat, Samba 2 Enterprise Linux, Samba 2024-11-21 2.5 Low
All versions of Samba prior to 4.13.16 are vulnerable to a malicious client using an SMB1 or NFS race to allow a directory to be created in an area of the server file system not exported under the share definition. Note that SMB1 has to be enabled, or the share also available via NFS in order for this attack to succeed.
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-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-2020-17049 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.
