CVE-2023-34967 | 4 Debian, Fedoraproject, Redhat and 1 more | 7 Debian Linux, Fedora, Enterprise Linux and 4 more | 2024-11-22 | 5.3 Medium |
A Type Confusion vulnerability was found in Samba's mdssvc RPC service for Spotlight. When parsing Spotlight mdssvc RPC packets, one encoded data structure is a key-value style dictionary where the keys are character strings, and the values can be any of the supported types in the mdssvc protocol. Due to a lack of type checking in callers of the dalloc_value_for_key() function, which returns the object associated with a key, a caller may trigger a crash in talloc_get_size() when talloc detects that the passed-in pointer is not a valid talloc pointer. With an RPC worker process shared among multiple client connections, a malicious client or attacker can trigger a process crash in a shared RPC mdssvc worker process, affecting all other clients this worker serves. | ||||
CVE-2023-34966 | 4 Debian, Fedoraproject, Redhat and 1 more | 7 Debian Linux, Fedora, Enterprise Linux and 4 more | 2024-11-22 | 7.5 High |
An infinite loop vulnerability was found in Samba's mdssvc RPC service for Spotlight. When parsing Spotlight mdssvc RPC packets sent by the client, the core unmarshalling function sl_unpack_loop() did not validate a field in the network packet that contains the count of elements in an array-like structure. By passing 0 as the count value, the attacked function will run in an endless loop consuming 100% CPU. This flaw allows an attacker to issue a malformed RPC request, triggering an infinite loop, resulting in a denial of service condition. | ||||
CVE-2023-4154 | 2 Redhat, Samba | 3 Enterprise Linux, Storage, Samba | 2024-11-21 | 7.5 High |
A design flaw was found in Samba's DirSync control implementation, which exposes passwords and secrets in Active Directory to privileged users and Read-Only Domain Controllers (RODCs). This flaw allows RODCs and users possessing the GET_CHANGES right to access all attributes, including sensitive secrets and passwords. Even in a default setup, RODC DC accounts, which should only replicate some passwords, can gain access to all domain secrets, including the vital krbtgt, effectively eliminating the RODC / DC distinction. Furthermore, the vulnerability fails to account for error conditions (fail open), like out-of-memory situations, potentially granting access to secret attributes, even under low-privileged attacker influence. | ||||
CVE-2022-3437 | 2 Fedoraproject, Samba | 2 Fedora, Samba | 2024-11-21 | 4.3 Medium |
A heap-based buffer overflow vulnerability was found in Samba within the GSSAPI unwrap_des() and unwrap_des3() routines of Heimdal. The DES and Triple-DES decryption routines in the Heimdal GSSAPI library allow a length-limited write buffer overflow on malloc() allocated memory when presented with a maliciously small packet. This flaw allows a remote user to send specially crafted malicious data to the application, possibly resulting in a denial of service (DoS) attack. | ||||
CVE-2022-32746 | 2 Redhat, Samba | 2 Enterprise Linux, Samba | 2024-11-21 | 5.4 Medium |
A flaw was found in the Samba AD LDAP server. The AD DC database audit logging module can access LDAP message values freed by a preceding database module, resulting in a use-after-free issue. This issue is only possible when modifying certain privileged attributes, such as userAccountControl. | ||||
CVE-2022-32745 | 1 Samba | 1 Samba | 2024-11-21 | 8.1 High |
A flaw was found in Samba. Samba AD users can cause the server to access uninitialized data with an LDAP add or modify the request, usually resulting in a segmentation fault. | ||||
CVE-2022-32744 | 1 Samba | 1 Samba | 2024-11-21 | 8.8 High |
A flaw was found in Samba. The KDC accepts kpasswd requests encrypted with any key known to it. By encrypting forged kpasswd requests with its own key, a user can change other users' passwords, enabling full domain takeover. | ||||
CVE-2022-32743 | 2 Fedoraproject, Samba | 2 Fedora, Samba | 2024-11-21 | 7.5 High |
Samba does not validate the Validated-DNS-Host-Name right for the dNSHostName attribute which could permit unprivileged users to write it. | ||||
CVE-2022-32742 | 2 Redhat, Samba | 4 Enterprise Linux, Rhev Hypervisor, Storage and 1 more | 2024-11-21 | 4.3 Medium |
A flaw was found in Samba. Some SMB1 write requests were not correctly range-checked to ensure the client had sent enough data to fulfill the write, allowing server memory contents to be written into the file (or printer) instead of client-supplied data. The client cannot control the area of the server memory written to the file (or printer). | ||||
CVE-2022-2031 | 1 Samba | 1 Samba | 2024-11-21 | 8.8 High |
A flaw was found in Samba. The security vulnerability occurs when KDC and the kpasswd service share a single account and set of keys, allowing them to decrypt each other's tickets. A user who has been requested to change their password, can exploit this flaw to obtain and use tickets to other services. | ||||
CVE-2022-1615 | 3 Fedoraproject, Redhat, Samba | 5 Fedora, Enterprise Linux, Rhel Eus and 2 more | 2024-11-21 | 5.5 Medium |
In Samba, GnuTLS gnutls_rnd() can fail and give predictable random values. | ||||
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-2021-44141 | 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. |
