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-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). 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.

CVE-2015-0240 4 Canonical, Novell, Redhat and 1 more 9 Ubuntu Linux, Suse Linux Enterprise Desktop, Suse Linux Enterprise Server and 6 more 2025-05-09 N/A
The Netlogon server implementation in smbd in Samba 3.5.x and 3.6.x before 3.6.25, 4.0.x before 4.0.25, 4.1.x before 4.1.17, and 4.2.x before 4.2.0rc5 performs a free operation on an uninitialized stack pointer, which allows remote attackers to execute arbitrary code via crafted Netlogon packets that use the ServerPasswordSet RPC API, as demonstrated by packets reaching the _netr_ServerPasswordSet function in rpc_server/netlogon/srv_netlog_nt.c.
CVE-2021-44142 6 Canonical, Debian, Fedoraproject and 3 more 28 Ubuntu Linux, Debian Linux, Fedora and 25 more 2025-04-23 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-2017-15275 4 Canonical, Debian, Redhat and 1 more 8 Ubuntu Linux, Debian Linux, Enterprise Linux and 5 more 2025-04-20 7.5 High
Samba before 4.7.3 might allow remote attackers to obtain sensitive information by leveraging failure of the server to clear allocated heap memory.
CVE-2017-11103 5 Apple, Debian, Freebsd and 2 more 6 Iphone Os, Mac Os X, Debian Linux and 3 more 2025-04-20 8.1 High
Heimdal before 7.4 allows remote attackers to impersonate services with Orpheus' Lyre attacks because it obtains service-principal names in a way that violates the Kerberos 5 protocol specification. In _krb5_extract_ticket() the KDC-REP service name must be obtained from the encrypted version stored in 'enc_part' instead of the unencrypted version stored in 'ticket'. Use of the unencrypted version provides an opportunity for successful server impersonation and other attacks. NOTE: this CVE is only for Heimdal and other products that embed Heimdal code; it does not apply to other instances in which this part of the Kerberos 5 protocol specification is violated.
CVE-2016-2126 2 Redhat, Samba 3 Enterprise Linux, Storage, Samba 2025-04-20 6.5 Medium
Samba version 4.0.0 up to 4.5.2 is vulnerable to privilege elevation due to incorrect handling of the PAC (Privilege Attribute Certificate) checksum. A remote, authenticated, attacker can cause the winbindd process to crash using a legitimate Kerberos ticket. A local service with access to the winbindd privileged pipe can cause winbindd to cache elevated access permissions.
CVE-2017-14746 4 Canonical, Debian, Redhat and 1 more 8 Ubuntu Linux, Debian Linux, Enterprise Linux and 5 more 2025-04-20 9.8 Critical
Use-after-free vulnerability in Samba 4.x before 4.7.3 allows remote attackers to execute arbitrary code via a crafted SMB1 request.
CVE-2017-9461 3 Debian, Redhat, Samba 10 Debian Linux, Enterprise Linux, Enterprise Linux Desktop and 7 more 2025-04-20 N/A
smbd in Samba before 4.4.10 and 4.5.x before 4.5.6 has a denial of service vulnerability (fd_open_atomic infinite loop with high CPU usage and memory consumption) due to wrongly handling dangling symlinks.
CVE-2022-44640 2 Heimdal Project, Samba 2 Heimdal, Samba 2025-04-15 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 2025-04-14 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-2016-2112 3 Canonical, Redhat, Samba 7 Ubuntu Linux, Enterprise Linux, Rhel Aus and 4 more 2025-04-12 N/A
The bundled LDAP client library in Samba 3.x and 4.x before 4.2.11, 4.3.x before 4.3.8, and 4.4.x before 4.4.2 does not recognize the "client ldap sasl wrapping" setting, which allows man-in-the-middle attackers to perform LDAP protocol-downgrade attacks by modifying the client-server data stream.
CVE-2016-0771 1 Samba 1 Samba 2025-04-12 N/A
The internal DNS server in Samba 4.x before 4.1.23, 4.2.x before 4.2.9, 4.3.x before 4.3.6, and 4.4.x before 4.4.0rc4, when an AD DC is configured, allows remote authenticated users to cause a denial of service (out-of-bounds read) or possibly obtain sensitive information from process memory by uploading a crafted DNS TXT record.
CVE-2016-2110 3 Canonical, Redhat, Samba 8 Ubuntu Linux, Enterprise Linux, Rhel Aus and 5 more 2025-04-12 N/A
The NTLMSSP authentication implementation in Samba 3.x and 4.x before 4.2.11, 4.3.x before 4.3.8, and 4.4.x before 4.4.2 allows man-in-the-middle attackers to perform protocol-downgrade attacks by modifying the client-server data stream to remove application-layer flags or encryption settings, as demonstrated by clearing the NTLMSSP_NEGOTIATE_SEAL or NTLMSSP_NEGOTIATE_SIGN option to disrupt LDAP security.
CVE-2015-7560 4 Canonical, Debian, Redhat and 1 more 5 Ubuntu Linux, Debian Linux, Enterprise Linux and 2 more 2025-04-12 6.5 Medium
The SMB1 implementation in smbd in Samba 3.x and 4.x before 4.1.23, 4.2.x before 4.2.9, 4.3.x before 4.3.6, and 4.4.x before 4.4.0rc4 allows remote authenticated users to modify arbitrary ACLs by using a UNIX SMB1 call to create a symlink, and then using a non-UNIX SMB1 call to write to the ACL content.
CVE-2013-6442 2 Redhat, Samba 2 Enterprise Linux, Samba 2025-04-12 N/A
The owner_set function in smbcacls.c in smbcacls in Samba 4.0.x before 4.0.16 and 4.1.x before 4.1.6 removes an ACL during use of a --chown or --chgrp option, which allows remote attackers to bypass intended access restrictions in opportunistic circumstances by leveraging an unintended administrative change.
CVE-2015-8467 3 Canonical, Debian, Samba 3 Ubuntu Linux, Debian Linux, Samba 2025-04-12 7.5 High
The samldb_check_user_account_control_acl function in dsdb/samdb/ldb_modules/samldb.c in Samba 4.x before 4.1.22, 4.2.x before 4.2.7, and 4.3.x before 4.3.3 does not properly check for administrative privileges during creation of machine accounts, which allows remote authenticated users to bypass intended access restrictions by leveraging the existence of a domain with both a Samba DC and a Windows DC, a similar issue to CVE-2015-2535.
CVE-2016-2119 2 Redhat, Samba 3 Enterprise Linux, Storage, Samba 2025-04-12 7.5 High
libcli/smb/smbXcli_base.c in Samba 4.x before 4.2.14, 4.3.x before 4.3.11, and 4.4.x before 4.4.5 allows man-in-the-middle attackers to bypass a client-signing protection mechanism, and consequently spoof SMB2 and SMB3 servers, via the (1) SMB2_SESSION_FLAG_IS_GUEST or (2) SMB2_SESSION_FLAG_IS_NULL flag.
CVE-2015-5296 4 Canonical, Debian, Redhat and 1 more 5 Ubuntu Linux, Debian Linux, Enterprise Linux and 2 more 2025-04-12 5.4 Medium
Samba 3.x and 4.x before 4.1.22, 4.2.x before 4.2.7, and 4.3.x before 4.3.3 supports connections that are encrypted but unsigned, which allows man-in-the-middle attackers to conduct encrypted-to-unencrypted downgrade attacks by modifying the client-server data stream, related to clidfs.c, libsmb_server.c, and smbXcli_base.c.
