| CVE-2021-20254 | 4 Debian, Fedoraproject, Redhat and 1 more | 9 Debian Linux, Fedora, Enterprise Linux and 6 more | 2024-08-03 | 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. | ||||
| CVE-2021-3670 | 3 Fedoraproject, Redhat, Samba | 3 Fedora, Storage, Samba | 2024-08-03 | 6.5 Medium |
| MaxQueryDuration not honoured in Samba AD DC LDAP | ||||
| CVE-2021-3671 | 3 Debian, Netapp, Samba | 5 Debian Linux, Management Services For Element Software, Management Services For Netapp Hci and 2 more | 2024-08-03 | 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-2021-3738 | 1 Samba | 1 Samba | 2024-08-03 | 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-2022-45141 | 1 Samba | 1 Samba | 2024-08-03 | 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-2022-44640 | 2 Heimdal Project, Samba | 2 Heimdal, Samba | 2024-08-03 | 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 | 2024-08-03 | 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-2022-38023 | 5 Fedoraproject, Microsoft, Netapp and 2 more | 18 Fedora, Windows Server 2008, Windows Server 2008 R2 and 15 more | 2024-08-03 | 8.1 High |
| Netlogon RPC Elevation of Privilege Vulnerability | ||||
| CVE-2022-37967 | 4 Fedoraproject, Microsoft, Netapp and 1 more | 12 Fedora, Windows Server 2008, Windows Server 2008 R2 and 9 more | 2024-08-03 | 7.2 High |
| 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 | 2024-08-03 | 8.1 High |
| Windows Kerberos RC4-HMAC Elevation of Privilege Vulnerability | ||||
| CVE-2022-32746 | 2 Redhat, Samba | 2 Enterprise Linux, Samba | 2024-08-03 | 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 | 2024-08-03 | 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-2022-32743 | 2 Fedoraproject, Samba | 2 Fedora, Samba | 2024-08-03 | 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 | 2 Redhat, Samba | 4 Enterprise Linux, Rhev Hypervisor, Storage and 1 more | 2024-08-03 | 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-2022-32744 | 1 Samba | 1 Samba | 2024-08-03 | 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-2022-3592 | 2 Fedoraproject, Samba | 2 Fedora, Samba | 2024-08-03 | 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-2022-3437 | 2 Fedoraproject, Samba | 2 Fedora, Samba | 2024-08-03 | 6.5 Medium |
| A heap-based buffer overflow vulnerability was found in Samba within the GSSAPI unwrap_des() and unwrap_des3() routines of Heimdal. The DES and Triple-DES decryption routines in the Heimdal GSSAPI library allow a length-limited write buffer overflow on malloc() allocated memory when presented with a maliciously small packet. This flaw allows a remote user to send specially crafted malicious data to the application, possibly resulting in a denial of service (DoS) attack. | ||||
| CVE-2022-2031 | 1 Samba | 1 Samba | 2024-08-03 | 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 | 3 Fedoraproject, Redhat, Samba | 5 Fedora, Enterprise Linux, Rhel Eus and 2 more | 2024-08-03 | 5.5 Medium |
| In Samba, GnuTLS gnutls_rnd() can fail and give predictable random values. | ||||
| CVE-2022-0336 | 2 Fedoraproject, Samba | 2 Fedora, Samba | 2024-08-02 | 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. | ||||
