| CVE-2022-37966 | 4 Fedoraproject, Microsoft, Netapp and 1 more | 9 Fedora, Windows Server 2008, Windows Server 2012 and 6 more | 2024-11-21 | N/A | 8.1 HIGH |
| Windows Kerberos RC4-HMAC Elevation of Privilege Vulnerability | |||||
| CVE-2022-32746 | 1 Samba | 1 Samba | 2024-11-21 | N/A | 5.4 MEDIUM |
| A flaw was found in the Samba AD LDAP server. The AD DC database audit logging module can access LDAP message values freed by a preceding database module, resulting in a use-after-free issue. This issue is only possible when modifying certain privileged attributes, such as userAccountControl. | |||||
| CVE-2022-32745 | 1 Samba | 1 Samba | 2024-11-21 | 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 | 2024-11-21 | 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-2022-32743 | 2 Fedoraproject, Samba | 2 Fedora, Samba | 2024-11-21 | N/A | 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-2022-32742 | 1 Samba | 1 Samba | 2024-11-21 | N/A | 4.3 MEDIUM |
| A flaw was found in Samba. Some SMB1 write requests were not correctly range-checked to ensure the client had sent enough data to fulfill the write, allowing server memory contents to be written into the file (or printer) instead of client-supplied data. The client cannot control the area of the server memory written to the file (or printer). | |||||
| CVE-2022-2127 | 4 Debian, Fedoraproject, Redhat and 1 more | 4 Debian Linux, Fedora, Enterprise Linux and 1 more | 2024-11-21 | N/A | 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-2022-2031 | 1 Samba | 1 Samba | 2024-11-21 | N/A | 8.8 HIGH |
| A flaw was found in Samba. The security vulnerability occurs when KDC and the kpasswd service share a single account and set of keys, allowing them to decrypt each other's tickets. A user who has been requested to change their password, can exploit this flaw to obtain and use tickets to other services. | |||||
| CVE-2022-1615 | 2 Fedoraproject, Samba | 2 Fedora, Samba | 2024-11-21 | N/A | 5.5 MEDIUM |
| In Samba, GnuTLS gnutls_rnd() can fail and give predictable random values. | |||||
| CVE-2022-0336 | 2 Fedoraproject, Samba | 2 Fedora, Samba | 2024-11-21 | N/A | 8.8 HIGH |
| The Samba AD DC includes checks when adding service principals names (SPNs) to an account to ensure that SPNs do not alias with those already in the database. Some of these checks are able to be bypassed if an account modification re-adds an SPN that was previously present on that account, such as one added when a computer is joined to a domain. An attacker who has the ability to write to an account can exploit this to perform a denial-of-service attack by adding an SPN that matches an existing service. Additionally, an attacker who can intercept traffic can impersonate existing services, resulting in a loss of confidentiality and integrity. | |||||
| CVE-2021-44142 | 6 Canonical, Debian, Fedoraproject and 3 more | 23 Ubuntu Linux, Debian Linux, Fedora and 20 more | 2024-11-21 | 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-2021-44141 | 3 Fedoraproject, Redhat, Samba | 3 Fedora, Storage, Samba | 2024-11-21 | 3.5 LOW | 4.3 MEDIUM |
| All versions of Samba prior to 4.15.5 are vulnerable to a malicious client using a server symlink to determine if a file or directory exists in an area of the server file system not exported under the share definition. SMB1 with unix extensions has to be enabled in order for this attack to succeed. | |||||
| CVE-2021-43566 | 1 Samba | 1 Samba | 2024-11-21 | 1.2 LOW | 2.5 LOW |
| All versions of Samba prior to 4.13.16 are vulnerable to a malicious client using an SMB1 or NFS race to allow a directory to be created in an area of the server file system not exported under the share definition. Note that SMB1 has to be enabled, or the share also available via NFS in order for this attack to succeed. | |||||
| CVE-2021-3738 | 1 Samba | 1 Samba | 2024-11-21 | 6.5 MEDIUM | 8.8 HIGH |
| In DCE/RPC it is possible to share the handles (cookies for resource state) between multiple connections via a mechanism called 'association groups'. These handles can reference connections to our sam.ldb database. However while the database was correctly shared, the user credentials state was only pointed at, and when one connection within that association group ended, the database would be left pointing at an invalid 'struct session_info'. The most likely outcome here is a crash, but it is possible that the use-after-free could instead allow different user state to be pointed at and this might allow more privileged access. | |||||
| CVE-2021-3671 | 3 Debian, Netapp, Samba | 5 Debian Linux, Management Services For Element Software, Management Services For Netapp Hci and 2 more | 2024-11-21 | 4.0 MEDIUM | 6.5 MEDIUM |
| A null pointer de-reference was found in the way samba kerberos server handled missing sname in TGS-REQ (Ticket Granting Server - Request). An authenticated user could use this flaw to crash the samba server. | |||||
| CVE-2021-3670 | 3 Fedoraproject, Redhat, Samba | 3 Fedora, Storage, Samba | 2024-11-21 | N/A | 6.5 MEDIUM |
| MaxQueryDuration not honoured in Samba AD DC LDAP | |||||
| CVE-2021-23192 | 1 Samba | 1 Samba | 2024-11-21 | 5.0 MEDIUM | 7.5 HIGH |
| A flaw was found in the way samba implemented DCE/RPC. If a client to a Samba server sent a very large DCE/RPC request, and chose to fragment it, an attacker could replace later fragments with their own data, bypassing the signature requirements. | |||||
| CVE-2021-20316 | 3 Debian, Redhat, Samba | 7 Debian Linux, Enterprise Linux, Enterprise Linux Aus and 4 more | 2024-11-21 | 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-2021-20277 | 3 Debian, Fedoraproject, Samba | 3 Debian Linux, Fedora, Samba | 2024-11-21 | 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. | |||||
| CVE-2021-20254 | 4 Debian, Fedoraproject, Redhat and 1 more | 4 Debian Linux, Fedora, Enterprise Linux and 1 more | 2024-11-21 | 4.9 MEDIUM | 6.8 MEDIUM |
| A flaw was found in samba. The Samba smbd file server must map Windows group identities (SIDs) into unix group ids (gids). The code that performs this had a flaw that could allow it to read data beyond the end of the array in the case where a negative cache entry had been added to the mapping cache. This could cause the calling code to return those values into the process token that stores the group membership for a user. The highest threat from this vulnerability is to data confidentiality and integrity. | |||||
