CVE-2023-42670 3 Fedoraproject, Redhat, Samba 4 Fedora, Enterprise Linux, Storage and 1 more 2025-08-30 6.5 Medium
A flaw was found in Samba. It is susceptible to a vulnerability where multiple incompatible RPC listeners can be initiated, causing disruptions in the AD DC service. When Samba's RPC server experiences a high load or unresponsiveness, servers intended for non-AD DC purposes (for example, NT4-emulation "classic DCs") can erroneously start and compete for the same unix domain sockets. This issue leads to partial query responses from the AD DC, causing issues such as "The procedure number is out of range" when using tools like Active Directory Users. This flaw allows an attacker to disrupt AD DC services.
CVE-2023-42669 2 Redhat, Samba 10 Enterprise Linux, Enterprise Linux Eus, Enterprise Linux For Ibm Z Systems and 7 more 2025-08-30 6.5 Medium
A vulnerability was found in Samba's "rpcecho" development server, a non-Windows RPC server used to test Samba's DCE/RPC stack elements. This vulnerability stems from an RPC function that can be blocked indefinitely. The issue arises because the "rpcecho" service operates with only one worker in the main RPC task, allowing calls to the "rpcecho" server to be blocked for a specified time, causing service disruptions. This disruption is triggered by a "sleep()" call in the "dcesrv_echo_TestSleep()" function under specific conditions. Authenticated users or attackers can exploit this vulnerability to make calls to the "rpcecho" server, requesting it to block for a specified duration, effectively disrupting most services and leading to a complete denial of service on the AD DC. The DoS affects all other services as "rpcecho" runs in the main RPC task.
CVE-2023-4091 3 Fedoraproject, Redhat, Samba 7 Fedora, Enterprise Linux, Enterprise Linux Eus and 4 more 2025-08-30 6.5 Medium
A vulnerability was discovered in Samba, where the flaw allows SMB clients to truncate files, even with read-only permissions when the Samba VFS module "acl_xattr" is configured with "acl_xattr:ignore system acls = yes". The SMB protocol allows opening files when the client requests read-only access but then implicitly truncates the opened file to 0 bytes if the client specifies a separate OVERWRITE create disposition request. The issue arises in configurations that bypass kernel file system permissions checks, relying solely on Samba's permissions.
CVE-2023-3961 3 Fedoraproject, Redhat, Samba 7 Fedora, Enterprise Linux, Enterprise Linux Eus and 4 more 2025-08-30 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-2023-34968 4 Debian, Fedoraproject, Redhat and 1 more 7 Debian Linux, Fedora, Enterprise Linux and 4 more 2025-08-30 5.3 Medium
A path disclosure vulnerability was found in Samba. As part of the Spotlight protocol, Samba discloses the server-side absolute path of shares, files, and directories in the results for search queries. This flaw allows a malicious client or an attacker with a targeted RPC request to view the information that is part of the disclosed path.
CVE-2023-34967 4 Debian, Fedoraproject, Redhat and 1 more 7 Debian Linux, Fedora, Enterprise Linux and 4 more 2025-08-30 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 2025-08-30 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-2023-3347 3 Fedoraproject, Redhat, Samba 4 Fedora, Enterprise Linux, Storage and 1 more 2025-08-30 5.9 Medium
A vulnerability was found in Samba's SMB2 packet signing mechanism. The SMB2 packet signing is not enforced if an admin configured "server signing = required" or for SMB2 connections to Domain Controllers where SMB2 packet signing is mandatory. This flaw allows an attacker to perform attacks, such as a man-in-the-middle attack, by intercepting the network traffic and modifying the SMB2 messages between client and server, affecting the integrity of the data.
CVE-2022-2127 4 Debian, Fedoraproject, Redhat and 1 more 7 Debian Linux, Fedora, Enterprise Linux and 4 more 2025-08-30 5.9 Medium
An out-of-bounds read vulnerability was found in Samba due to insufficient length checks in winbindd_pam_auth_crap.c. When performing NTLM authentication, the client replies to cryptographic challenges back to the server. These replies have variable lengths, and Winbind fails to check the lan manager response length. When Winbind is used for NTLM authentication, a maliciously crafted request can trigger an out-of-bounds read in Winbind, possibly resulting in a crash.
CVE-2022-1615 3 Fedoraproject, Redhat, Samba 5 Fedora, Enterprise Linux, Rhel Eus and 2 more 2025-08-22 5.5 Medium
In Samba, GnuTLS gnutls_rnd() can fail and give predictable random values.
CVE-2022-32743 2 Fedoraproject, Samba 2 Fedora, Samba 2025-08-22 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-2021-3670 3 Fedoraproject, Redhat, Samba 3 Fedora, Storage, Samba 2025-08-21 6.5 Medium
MaxQueryDuration not honoured in Samba AD DC LDAP
CVE-2025-0620 2 Redhat, Samba 3 Enterprise Linux, Openshift, Samba 2025-08-13 6.6 Medium
A flaw was found in Samba. The smbd service daemon does not pick up group membership changes when re-authenticating an expired SMB session. This issue can expose file shares until clients disconnect and then connect again.
CVE-2024-12088 8 Almalinux, Archlinux, Gentoo and 5 more 21 Almalinux, Arch Linux, Linux and 18 more 2025-08-13 6.5 Medium
A flaw was found in rsync. When using the `--safe-links` option, the rsync client fails to properly verify if a symbolic link destination sent from the server contains another symbolic link within it. This results in a path traversal vulnerability, which may lead to arbitrary file write outside the desired directory.
CVE-2024-12087 8 Almalinux, Archlinux, Gentoo and 5 more 20 Almalinux, Arch Linux, Linux and 17 more 2025-08-13 6.5 Medium
A path traversal vulnerability exists in rsync. It stems from behavior enabled by the `--inc-recursive` option, a default-enabled option for many client options and can be enabled by the server even if not explicitly enabled by the client. When using the `--inc-recursive` option, a lack of proper symlink verification coupled with deduplication checks occurring on a per-file-list basis could allow a server to write files outside of the client's intended destination directory. A malicious server could write malicious files to arbitrary locations named after valid directories/paths on the client.
CVE-2024-12085 8 Almalinux, Archlinux, Gentoo and 5 more 28 Almalinux, Arch Linux, Linux and 25 more 2025-08-13 7.5 High
A flaw was found in rsync which could be triggered when rsync compares file checksums. This flaw allows an attacker to manipulate the checksum length (s2length) to cause a comparison between a checksum and uninitialized memory and leak one byte of uninitialized stack data at a time.
CVE-2017-7494 3 Debian, Redhat, Samba 9 Debian Linux, Enterprise Linux, Rhel Aus and 6 more 2025-07-30 9.8 Critical
Samba since version 3.5.0 and before 4.6.4, 4.5.10 and 4.4.14 is vulnerable to remote code execution vulnerability, allowing a malicious client to upload a shared library to a writable share, and then cause the server to load and execute it.
CVE-2020-1472 9 Canonical, Debian, Fedoraproject and 6 more 20 Ubuntu Linux, Debian Linux, Fedora and 17 more 2025-07-30 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).

CVE-2024-12086 8 Almalinux, Archlinux, Gentoo and 5 more 10 Almalinux, Arch Linux, Linux and 7 more 2025-07-29 6.1 Medium
A flaw was found in rsync. It could allow a server to enumerate the contents of an arbitrary file from the client's machine. This issue occurs when files are being copied from a client to a server. During this process, the rsync server will send checksums of local data to the client to compare with in order to determine what data needs to be sent to the server. By sending specially constructed checksum values for arbitrary files, an attacker may be able to reconstruct the data of those files byte-by-byte based on the responses from the client.
CVE-2024-12084 8 Almalinux, Archlinux, Gentoo and 5 more 9 Almalinux, Arch Linux, Linux and 6 more 2025-07-29 9.8 Critical
A heap-based buffer overflow flaw was found in the rsync daemon. This issue is due to improper handling of attacker-controlled checksum lengths (s2length) in the code. When MAX_DIGEST_LEN exceeds the fixed SUM_LENGTH (16 bytes), an attacker can write out of bounds in the sum2 buffer.
