|---|---|---|---|---|---|
| CVE-2019-14907 | 6 Canonical, Debian, Fedoraproject and 3 more | 10 Ubuntu Linux, Debian Linux, Fedora and 7 more | 2023-11-07 | 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-2019-14902 | 4 Canonical, Debian, Opensuse and 1 more | 4 Ubuntu Linux, Debian Linux, Leap and 1 more | 2023-11-07 | 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-2019-14870 | 5 Canonical, Debian, Fedoraproject and 2 more | 5 Ubuntu Linux, Debian Linux, Fedora and 2 more | 2023-11-07 | 6.4 MEDIUM | 5.4 MEDIUM |
| All Samba versions 4.x.x before 4.9.17, 4.10.x before 4.10.11 and 4.11.x before 4.11.3 have an issue, where the S4U (MS-SFU) Kerberos delegation model includes a feature allowing for a subset of clients to be opted out of constrained delegation in any way, either S4U2Self or regular Kerberos authentication, by forcing all tickets for these clients to be non-forwardable. In AD this is implemented by a user attribute delegation_not_allowed (aka not-delegated), which translates to disallow-forwardable. However the Samba AD DC does not do that for S4U2Self and does set the forwardable flag even if the impersonated client has the not-delegated flag set. | |||||
| CVE-2019-14847 | 3 Fedoraproject, Opensuse, Samba | 3 Fedora, Leap, Samba | 2023-11-07 | 4.0 MEDIUM | 4.9 MEDIUM |
| A flaw was found in samba 4.0.0 before samba 4.9.15 and samba 4.10.x before 4.10.10. An attacker can crash AD DC LDAP server via dirsync resulting in denial of service. Privilege escalation is not possible with this issue. | |||||
| CVE-2019-14833 | 3 Fedoraproject, Opensuse, Samba | 3 Fedora, Leap, Samba | 2023-11-07 | 4.9 MEDIUM | 5.4 MEDIUM |
| A flaw was found in Samba, all versions starting samba 4.5.0 before samba 4.9.15, samba 4.10.10, samba 4.11.2, in the way it handles a user password change or a new password for a samba user. The Samba Active Directory Domain Controller can be configured to use a custom script to check for password complexity. This configuration can fail to verify password complexity when non-ASCII characters are used in the password, which could lead to weak passwords being set for samba users, making it vulnerable to dictionary attacks. | |||||
| CVE-2019-12436 | 2 Canonical, Samba | 2 Ubuntu Linux, Samba | 2023-11-07 | 4.0 MEDIUM | 6.5 MEDIUM |
| Samba 4.10.x before 4.10.5 has a NULL pointer dereference, leading to an AD DC LDAP server Denial of Service. This is related to an attacker using the paged search control. The attacker must have directory read access in order to attempt an exploit. | |||||
| CVE-2019-12435 | 1 Samba | 1 Samba | 2023-11-07 | 4.0 MEDIUM | 6.5 MEDIUM |
| Samba 4.9.x before 4.9.9 and 4.10.x before 4.10.5 has a NULL pointer dereference, leading to Denial of Service. This is related to the AD DC DNS management server (dnsserver) RPC server process. | |||||
| CVE-2019-10218 | 2 Fedoraproject, Samba | 2 Fedora, Samba | 2023-11-07 | 4.3 MEDIUM | 6.5 MEDIUM |
| A flaw was found in the samba client, all samba versions before samba 4.11.2, 4.10.10 and 4.9.15, where a malicious server can supply a pathname to the client with separators. This could allow the client to access files and folders outside of the SMB network pathnames. An attacker could use this vulnerability to create files outside of the current working directory using the privileges of the client user. | |||||
| CVE-2019-10197 | 3 Canonical, Debian, Samba | 3 Ubuntu Linux, Debian Linux, Samba | 2023-11-07 | 6.4 MEDIUM | 9.1 CRITICAL |
| A flaw was found in samba versions 4.9.x up to 4.9.13, samba 4.10.x up to 4.10.8 and samba 4.11.x up to 4.11.0rc3, when certain parameters were set in the samba configuration file. An unauthenticated attacker could use this flaw to escape the shared directory and access the contents of directories outside the share. | |||||
| CVE-2017-9461 | 3 Debian, Redhat, Samba | 8 Debian Linux, Enterprise Linux Desktop, Enterprise Linux Server and 5 more | 2023-11-07 | 6.8 MEDIUM | 6.5 MEDIUM |
| 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-2016-2125 | 2 Redhat, Samba | 8 Enterprise Linux Desktop, Enterprise Linux Server, Enterprise Linux Server Aus and 5 more | 2023-11-07 | 3.3 LOW | 6.5 MEDIUM |
| It was found that Samba before versions 4.5.3, 4.4.8, 4.3.13 always requested forwardable tickets when using Kerberos authentication. A service to which Samba authenticated using Kerberos could subsequently use the ticket to impersonate Samba to other services or domain users. | |||||
| CVE-2015-8467 | 3 Canonical, Debian, Samba | 3 Ubuntu Linux, Debian Linux, Samba | 2023-11-07 | 6.0 MEDIUM | 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-2015-7540 | 3 Canonical, Debian, Samba | 3 Ubuntu Linux, Debian Linux, Samba | 2023-11-07 | 5.0 MEDIUM | 7.5 HIGH |
| The LDAP server in the AD domain controller in Samba 4.x before 4.1.22 does not check return values to ensure successful ASN.1 memory allocation, which allows remote attackers to cause a denial of service (memory consumption and daemon crash) via crafted packets. | |||||
| CVE-2015-5330 | 1 Samba | 1 Samba | 2023-11-07 | 5.0 MEDIUM | 7.5 HIGH |
| ldb before 1.1.24, as used in the AD LDAP server in Samba 4.x before 4.1.22, 4.2.x before 4.2.7, and 4.3.x before 4.3.3, mishandles string lengths, which allows remote attackers to obtain sensitive information from daemon heap memory by sending crafted packets and then reading (1) an error message or (2) a database value. | |||||
| CVE-2015-5299 | 3 Canonical, Debian, Samba | 3 Ubuntu Linux, Debian Linux, Samba | 2023-11-07 | 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-2015-5296 | 3 Canonical, Debian, Samba | 3 Ubuntu Linux, Debian Linux, Samba | 2023-11-07 | 4.3 MEDIUM | 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. | |||||
| CVE-2015-5252 | 3 Canonical, Debian, Samba | 3 Ubuntu Linux, Debian Linux, Samba | 2023-11-07 | 5.0 MEDIUM | 7.2 HIGH |
| vfs.c in smbd 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, when share names with certain substring relationships exist, allows remote attackers to bypass intended file-access restrictions via a symlink that points outside of a share. | |||||
| CVE-2015-3223 | 1 Samba | 1 Samba | 2023-11-07 | 5.0 MEDIUM | 5.3 MEDIUM |
| The ldb_wildcard_compare function in ldb_match.c in ldb before 1.1.24, as used in the AD LDAP server in Samba 4.x before 4.1.22, 4.2.x before 4.2.7, and 4.3.x before 4.3.3, mishandles certain zero values, which allows remote attackers to cause a denial of service (infinite loop) via crafted packets. | |||||
| CVE-2014-3560 | 3 Canonical, Redhat, Samba | 3 Ubuntu Linux, Enterprise Linux, Samba | 2023-11-07 | 7.9 HIGH | N/A |
| NetBIOS name services daemon (nmbd) in Samba 4.0.x before 4.0.21 and 4.1.x before 4.1.11 allows remote attackers to execute arbitrary code via unspecified vectors that modify heap memory, involving a sizeof operation on an incorrect variable in the unstrcpy macro in string_wrappers.h. | |||||
| CVE-2011-2724 | 1 Samba | 1 Samba | 2023-11-07 | 1.2 LOW | N/A |
| The check_mtab function in client/mount.cifs.c in mount.cifs in smbfs in Samba 3.5.10 and earlier does not properly verify that the (1) device name and (2) mountpoint strings are composed of valid characters, which allows local users to cause a denial of service (mtab corruption) via a crafted string. NOTE: this vulnerability exists because of an incorrect fix for CVE-2010-0547. | |||||
