CVE-2025-0620 1 Samba 1 Samba 2025-08-13 N/A 4.9 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-2021-44142 6 Canonical, Debian, Fedoraproject and 3 more 23 Ubuntu Linux, Debian Linux, Fedora and 20 more 2025-04-23 9.0 HIGH 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-2022-44640 2 Heimdal Project, Samba 2 Heimdal, Samba 2025-04-15 N/A 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 3 Heimdal Project, Mit, Samba 3 Heimdal, Kerberos 5, Samba 2025-04-14 N/A 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 2025-04-08 N/A 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-2017-7494 2 Debian, Samba 2 Debian Linux, Samba 2025-04-03 10.0 HIGH 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 8 Canonical, Debian, Fedoraproject and 5 more 15 Ubuntu Linux, Debian Linux, Fedora and 12 more 2025-03-07 9.3 HIGH N/A
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-2022-45141 1 Samba 1 Samba 2025-03-06 N/A 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-2023-0225 1 Samba 1 Samba 2025-02-18 N/A 4.3 MEDIUM
A flaw was found in Samba. An incomplete access check on dnsHostName allows authenticated but otherwise unprivileged users to delete this attribute from any object in the directory.
CVE-2023-0922 1 Samba 1 Samba 2025-02-13 N/A 5.9 MEDIUM
The Samba AD DC administration tool, when operating against a remote LDAP server, will by default send new or reset passwords over a signed-only connection.
CVE-2023-0614 1 Samba 1 Samba 2025-02-13 N/A 6.5 MEDIUM
The fix in 4.6.16, 4.7.9, 4.8.4 and 4.9.7 for CVE-2018-10919 Confidential attribute disclosure vi LDAP filters was insufficient and an attacker may be able to obtain confidential BitLocker recovery keys from a Samba AD DC.
CVE-2018-14628 2 Fedoraproject, Samba 2 Fedora, Samba 2025-01-22 N/A 4.3 MEDIUM
An information leak vulnerability was discovered in Samba's LDAP server. Due to missing access control checks, an authenticated but unprivileged attacker could discover the names and preserved attributes of deleted objects in the LDAP store.
CVE-2019-14907 6 Canonical, Debian, Fedoraproject and 3 more 10 Ubuntu Linux, Debian Linux, Fedora and 7 more 2025-01-14 2.6 LOW 6.5 MEDIUM
All samba versions 4.9.x before 4.9.18, 4.10.x before 4.10.12 and 4.11.x before 4.11.5 have an issue where if it is set with "log level = 3" (or above) then the string obtained from the client, after a failed character conversion, is printed. Such strings can be provided during the NTLMSSP authentication exchange. In the Samba AD DC in particular, this may cause a long-lived process(such as the RPC server) to terminate. (In the file server case, the most likely target, smbd, operates as process-per-client and so a crash there is harmless).
CVE-2019-3870 3 Fedoraproject, Samba, Synology 9 Fedora, Samba, Directory Server and 6 more 2025-01-14 3.6 LOW 6.1 MEDIUM
A vulnerability was found in Samba from version (including) 4.9 to versions before 4.9.6 and 4.10.2. During the creation of a new Samba AD DC, files are created in a private subdirectory of the install location. This directory is typically mode 0700, that is owner (root) only access. However in some upgraded installations it will have other permissions, such as 0755, because this was the default before Samba 4.8. Within this directory, files are created with mode 0666, which is world-writable, including a sample krb5.conf, and the list of DNS names and servicePrincipalName values to update.
CVE-2019-19344 4 Canonical, Opensuse, Samba and 1 more 7 Ubuntu Linux, Leap, Samba and 4 more 2025-01-14 4.0 MEDIUM 6.5 MEDIUM
There is a use-after-free issue in all samba 4.9.x versions before 4.9.18, all samba 4.10.x versions before 4.10.12 and all samba 4.11.x versions before 4.11.5, essentially due to a call to realloc() while other local variables still point at the original buffer.
CVE-2022-37967 4 Fedoraproject, Microsoft, Netapp and 1 more 9 Fedora, Windows Server 2008, Windows Server 2012 and 6 more 2025-01-02 N/A N/A
Windows Kerberos Elevation of Privilege Vulnerability
CVE-2022-37966 4 Fedoraproject, Microsoft, Netapp and 1 more 9 Fedora, Windows Server 2008, Windows Server 2012 and 6 more 2025-01-02 N/A N/A
Windows Kerberos RC4-HMAC Elevation of Privilege Vulnerability
CVE-2022-38023 4 Fedoraproject, Microsoft, Netapp and 1 more 9 Fedora, Windows Server 2008, Windows Server 2012 and 6 more 2025-01-02 N/A N/A
Netlogon RPC Elevation of Privilege Vulnerability
CVE-2023-3347 3 Fedoraproject, Redhat, Samba 4 Fedora, Enterprise Linux, Storage and 1 more 2024-12-06 N/A 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-2023-34968 4 Debian, Fedoraproject, Redhat and 1 more 5 Debian Linux, Fedora, Enterprise Linux and 2 more 2024-12-06 N/A 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.
