CVE-2015-5299 3 Canonical, Debian, Samba 3 Ubuntu Linux, Debian Linux, Samba 2022-08-29 5.0 MEDIUM 5.3 MEDIUM
The shadow_copy2_get_shadow_copy_data function in modules/vfs_shadow_copy2.c in 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 does not verify that the DIRECTORY_LIST access right has been granted, which allows remote attackers to access snapshots by visiting a shadow copy directory.
CVE-2004-0686 2 Samba, Trustix 2 Samba, Secure Linux 2022-08-29 5.0 MEDIUM N/A
Buffer overflow in Samba 2.2.x to 2.2.9, and 3.0.0 to 3.0.4, when the "mangling method = hash" option is enabled in smb.conf, has unknown impact and attack vectors.
CVE-2013-4496 2 Canonical, Samba 2 Ubuntu Linux, Samba 2022-08-29 5.0 MEDIUM N/A
Samba 3.x before 3.6.23, 4.0.x before 4.0.16, and 4.1.x before 4.1.6 does not enforce the password-guessing protection mechanism for all interfaces, which makes it easier for remote attackers to obtain access via brute-force ChangePasswordUser2 (1) SAMR or (2) RAP attempts.
CVE-2018-16841 3 Canonical, Debian, Samba 3 Ubuntu Linux, Debian Linux, Samba 2022-08-29 4.0 MEDIUM 6.5 MEDIUM
Samba from version 4.3.0 and before versions 4.7.12, 4.8.7 and 4.9.3 are vulnerable to a denial of service. When configured to accept smart-card authentication, Samba's KDC will call talloc_free() twice on the same memory if the principal in a validly signed certificate does not match the principal in the AS-REQ. This is only possible after authentication with a trusted certificate. talloc is robust against further corruption from a double-free with talloc_free() and directly calls abort(), terminating the KDC process.
CVE-2014-0239 1 Samba 1 Samba 2022-08-29 5.0 MEDIUM N/A
The internal DNS server in Samba 4.x before 4.0.18 does not check the QR field in the header section of an incoming DNS message before sending a response, which allows remote attackers to cause a denial of service (CPU and bandwidth consumption) via a forged response packet that triggers a communication loop, a related issue to CVE-1999-0103.
CVE-2015-7560 3 Canonical, Debian, Samba 3 Ubuntu Linux, Debian Linux, Samba 2022-08-29 4.0 MEDIUM 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-2018-16851 3 Canonical, Debian, Samba 3 Ubuntu Linux, Debian Linux, Samba 2022-08-29 4.0 MEDIUM 6.5 MEDIUM
Samba from version 4.0.0 and before versions 4.7.12, 4.8.7, 4.9.3 is vulnerable to a denial of service. During the processing of an LDAP search before Samba's AD DC returns the LDAP entries to the client, the entries are cached in a single memory object with a maximum size of 256MB. When this size is reached, the Samba process providing the LDAP service will follow the NULL pointer, terminating the process. There is no further vulnerability associated with this issue, merely a denial of service.
CVE-2019-3880 5 Debian, Fedoraproject, Opensuse and 2 more 6 Debian Linux, Fedora, Leap and 3 more 2022-08-29 5.5 MEDIUM 5.4 MEDIUM
A flaw was found in the way samba implemented an RPC endpoint emulating the Windows registry service API. An unprivileged attacker could use this flaw to create a new registry hive file anywhere they have unix permissions which could lead to creation of a new file in the Samba share. Versions before 4.8.11, 4.9.6 and 4.10.2 are vulnerable.
CVE-2016-2126 1 Samba 1 Samba 2022-08-29 4.0 MEDIUM 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-2019-14902 4 Canonical, Debian, Opensuse and 1 more 4 Ubuntu Linux, Debian Linux, Leap and 1 more 2022-08-29 5.5 MEDIUM 5.4 MEDIUM
There is an issue in all samba 4.11.x versions before 4.11.5, all samba 4.10.x versions before 4.10.12 and all samba 4.9.x versions before 4.9.18, where the removal of the right to create or modify a subtree would not automatically be taken away on all domain controllers.
CVE-2009-1888 3 Canonical, Debian, Samba 3 Ubuntu Linux, Debian Linux, Samba 2022-08-29 5.8 MEDIUM N/A
The acl_group_override function in smbd/posix_acls.c in smbd in Samba 3.0.x before 3.0.35, 3.1.x and 3.2.x before 3.2.13, and 3.3.x before 3.3.6, when dos filemode is enabled, allows remote attackers to modify access control lists for files via vectors related to read access to uninitialized memory.
CVE-2021-3670 3 Fedoraproject, Redhat, Samba 3 Fedora, Storage, Samba 2022-08-29 N/A 6.5 MEDIUM
MaxQueryDuration not honoured in Samba AD DC LDAP
CVE-2022-32745 1 Samba 1 Samba 2022-08-29 N/A 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 2022-08-29 N/A 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-2021-20316 3 Debian, Redhat, Samba 7 Debian Linux, Enterprise Linux, Enterprise Linux Aus and 4 more 2022-08-26 N/A 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-1999-0810 1 Samba 1 Samba 2022-08-17 10.0 HIGH N/A
Denial of service in Samba NETBIOS name service daemon (nmbd).
CVE-1999-0812 1 Samba 1 Samba 2022-08-17 7.6 HIGH N/A
Race condition in Samba smbmnt allows local users to mount file systems in arbitrary locations.
CVE-2017-7494 2 Debian, Samba 2 Debian Linux, Samba 2022-08-16 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-2017-14746 4 Canonical, Debian, Redhat and 1 more 6 Ubuntu Linux, Debian Linux, Enterprise Linux Desktop and 3 more 2022-08-16 7.5 HIGH 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-2021-20277 3 Debian, Fedoraproject, Samba 3 Debian Linux, Fedora, Samba 2022-08-05 5.0 MEDIUM 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.
