| CVE-2023-3961 | 3 Fedoraproject, Redhat, Samba | 7 Fedora, Enterprise Linux, Enterprise Linux Eus and 4 more | 2024-11-23 | 9.1 Critical |
| A path traversal vulnerability was identified in Samba when processing client pipe names connecting to Unix domain sockets within a private directory. Samba typically uses this mechanism to connect SMB clients to remote procedure call (RPC) services like SAMR LSA or SPOOLSS, which Samba initiates on demand. However, due to inadequate sanitization of incoming client pipe names, allowing a client to send a pipe name containing Unix directory traversal characters (../). This could result in SMB clients connecting as root to Unix domain sockets outside the private directory. If an attacker or client managed to send a pipe name resolving to an external service using an existing Unix domain socket, it could potentially lead to unauthorized access to the service and consequential adverse events, including compromise or service crashes. | ||||
| 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-2022-45141 | 1 Samba | 1 Samba | 2024-11-21 | 9.8 Critical |
| Since the Windows Kerberos RC4-HMAC Elevation of Privilege Vulnerability was disclosed by Microsoft on Nov 8 2022 and per RFC8429 it is assumed that rc4-hmac is weak, Vulnerable Samba Active Directory DCs will issue rc4-hmac encrypted tickets despite the target server supporting better encryption (eg aes256-cts-hmac-sha1-96). | ||||
| CVE-2022-44640 | 2 Heimdal Project, Samba | 2 Heimdal, Samba | 2024-11-21 | 9.8 Critical |
| Heimdal before 7.7.1 allows remote attackers to execute arbitrary code because of an invalid free in the ASN.1 codec used by the Key Distribution Center (KDC). | ||||
| CVE-2022-42898 | 4 Heimdal Project, Mit, Redhat and 1 more | 10 Heimdal, Kerberos 5, Enterprise Linux and 7 more | 2024-11-21 | 8.8 High |
| PAC parsing in MIT Kerberos 5 (aka krb5) before 1.19.4 and 1.20.x before 1.20.1 has integer overflows that may lead to remote code execution (in KDC, kadmind, or a GSS or Kerberos application server) on 32-bit platforms (which have a resultant heap-based buffer overflow), and cause a denial of service on other platforms. This occurs in krb5_pac_parse in lib/krb5/krb/pac.c. Heimdal before 7.7.1 has "a similar bug." | ||||
| CVE-2022-3592 | 2 Fedoraproject, Samba | 2 Fedora, Samba | 2024-11-21 | 6.5 Medium |
| A symlink following vulnerability was found in Samba, where a user can create a symbolic link that will make 'smbd' escape the configured share path. This flaw allows a remote user with access to the exported part of the file system under a share via SMB1 unix extensions or NFS to create symlinks to files outside the 'smbd' configured share path and gain access to another restricted server's filesystem. | ||||
| 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-2021-44142 | 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. | ||||
