CVE-2022-45141 | 1 Samba | 1 Samba | 2023-12-10 | N/A | 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-2022-42898 | 3 Heimdal Project, Mit, Samba | 3 Heimdal, Kerberos 5, Samba | 2023-12-10 | N/A | 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-2022-44640 | 2 Heimdal Project, Samba | 2 Heimdal, Samba | 2023-12-10 | N/A | 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-2022-3437 | 2 Fedoraproject, Samba | 2 Fedora, Samba | 2023-12-10 | N/A | 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-2021-20251 | 2 Fedoraproject, Samba | 2 Fedora, Samba | 2023-12-10 | N/A | 5.9 MEDIUM |
A flaw was found in samba. A race condition in the password lockout code may lead to the risk of brute force attacks being successful if special conditions are met. | |||||
CVE-2022-3592 | 2 Fedoraproject, Samba | 2 Fedora, Samba | 2023-12-10 | N/A | 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-2022-1615 | 2 Fedoraproject, Samba | 2 Fedora, Samba | 2023-12-10 | N/A | 5.5 MEDIUM |
In Samba, GnuTLS gnutls_rnd() can fail and give predictable random values. | |||||
CVE-2022-32746 | 1 Samba | 1 Samba | 2023-12-10 | 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-2022-32744 | 1 Samba | 1 Samba | 2023-12-10 | 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 | 2023-12-10 | 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-2022-2031 | 1 Samba | 1 Samba | 2023-12-10 | 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-2022-32745 | 1 Samba | 1 Samba | 2023-12-10 | 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-2022-0336 | 2 Fedoraproject, Samba | 2 Fedora, Samba | 2023-12-10 | 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-2022-32742 | 1 Samba | 1 Samba | 2023-12-10 | 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-2022-29154 | 2 Fedoraproject, Samba | 2 Fedora, Rsync | 2023-12-10 | N/A | 7.4 HIGH |
An issue was discovered in rsync before 3.2.5 that allows malicious remote servers to write arbitrary files inside the directories of connecting peers. The server chooses which files/directories are sent to the client. However, the rsync client performs insufficient validation of file names. A malicious rsync server (or Man-in-The-Middle attacker) can overwrite arbitrary files in the rsync client target directory and subdirectories (for example, overwrite the .ssh/authorized_keys file). | |||||
CVE-2022-38023 | 4 Fedoraproject, Microsoft, Netapp and 1 more | 9 Fedora, Windows Server 2008, Windows Server 2012 and 6 more | 2023-12-10 | N/A | 8.1 HIGH |
Netlogon RPC Elevation of Privilege Vulnerability | |||||
CVE-2021-20316 | 3 Debian, Redhat, Samba | 7 Debian Linux, Enterprise Linux, Enterprise Linux Aus and 4 more | 2023-12-10 | 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-2021-3670 | 3 Fedoraproject, Redhat, Samba | 3 Fedora, Storage, Samba | 2023-12-10 | N/A | 6.5 MEDIUM |
MaxQueryDuration not honoured in Samba AD DC LDAP | |||||

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 | 2023-12-10 | N/A | 8.1 HIGH |
