| CVE-2020-14383 | 2 Redhat, Samba | 2 Enterprise Linux, Samba | 2024-04-22 | 4.0 MEDIUM | 6.5 MEDIUM |
| A flaw was found in samba's DNS server. An authenticated user could use this flaw to the RPC server to crash. This RPC server, which also serves protocols other than dnsserver, will be restarted after a short delay, but it is easy for an authenticated non administrative attacker to crash it again as soon as it returns. The Samba DNS server itself will continue to operate, but many RPC services will not. | |||||
| CVE-2004-1002 | 2 Canonical, Samba | 2 Ubuntu Linux, Ppp | 2024-02-08 | 5.0 MEDIUM | 7.5 HIGH |
| Integer underflow in pppd in cbcp.c for ppp 2.4.1 allows remote attackers to cause a denial of service (daemon crash) via a CBCP packet with an invalid length value that causes pppd to access an incorrect memory location. | |||||
| CVE-2016-2123 | 1 Samba | 1 Samba | 2024-02-08 | 6.5 MEDIUM | 8.8 HIGH |
| A flaw was found in samba versions 4.0.0 to 4.5.2. The Samba routine ndr_pull_dnsp_name contains an integer wrap problem, leading to an attacker-controlled memory overwrite. ndr_pull_dnsp_name parses data from the Samba Active Directory ldb database. Any user who can write to the dnsRecord attribute over LDAP can trigger this memory corruption. By default, all authenticated LDAP users can write to the dnsRecord attribute on new DNS objects. This makes the defect a remote privilege escalation. | |||||
| CVE-2023-4154 | 1 Samba | 1 Samba | 2023-12-29 | N/A | 6.5 MEDIUM |
| A design flaw was found in Samba's DirSync control implementation, which exposes passwords and secrets in Active Directory to privileged users and Read-Only Domain Controllers (RODCs). This flaw allows RODCs and users possessing the GET_CHANGES right to access all attributes, including sensitive secrets and passwords. Even in a default setup, RODC DC accounts, which should only replicate some passwords, can gain access to all domain secrets, including the vital krbtgt, effectively eliminating the RODC / DC distinction. Furthermore, the vulnerability fails to account for error conditions (fail open), like out-of-memory situations, potentially granting access to secret attributes, even under low-privileged attacker influence. | |||||
| CVE-2022-27239 | 5 Debian, Fedoraproject, Hp and 2 more | 19 Debian Linux, Fedora, Helion Openstack and 16 more | 2023-11-24 | 7.2 HIGH | 7.8 HIGH |
| In cifs-utils through 6.14, a stack-based buffer overflow when parsing the mount.cifs ip= command-line argument could lead to local attackers gaining root privileges. | |||||
| CVE-2022-29869 | 3 Debian, Fedoraproject, Samba | 3 Debian Linux, Fedora, Cifs-utils | 2023-11-24 | 4.3 MEDIUM | 5.3 MEDIUM |
| cifs-utils through 6.14, with verbose logging, can cause an information leak when a file contains = (equal sign) characters but is not a valid credentials file. | |||||
| CVE-2022-32743 | 2 Fedoraproject, Samba | 2 Fedora, Samba | 2023-11-07 | 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-2022-32745 | 1 Samba | 1 Samba | 2023-11-07 | 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-2022-29154 | 2 Fedoraproject, Samba | 2 Fedora, Rsync | 2023-11-07 | 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-2022-1615 | 2 Fedoraproject, Samba | 2 Fedora, Samba | 2023-11-07 | N/A | 5.5 MEDIUM |
| In Samba, GnuTLS gnutls_rnd() can fail and give predictable random values. | |||||
| CVE-2021-3671 | 3 Debian, Netapp, Samba | 5 Debian Linux, Management Services For Element Software, Management Services For Netapp Hci and 2 more | 2023-11-07 | 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-2021-20208 | 3 Fedoraproject, Redhat, Samba | 3 Fedora, Enterprise Linux, Cifs-utils | 2023-11-07 | 4.9 MEDIUM | 6.1 MEDIUM |
| A flaw was found in cifs-utils in versions before 6.13. A user when mounting a krb5 CIFS file system from within a container can use Kerberos credentials of the host. The highest threat from this vulnerability is to data confidentiality and integrity. | |||||
| CVE-2021-20254 | 4 Debian, Fedoraproject, Redhat and 1 more | 4 Debian Linux, Fedora, Enterprise Linux and 1 more | 2023-11-07 | 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. | |||||
| CVE-2021-20277 | 3 Debian, Fedoraproject, Samba | 3 Debian Linux, Fedora, Samba | 2023-11-07 | 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-2020-27840 | 3 Debian, Fedoraproject, Samba | 3 Debian Linux, Fedora, Samba | 2023-11-07 | 5.0 MEDIUM | 7.5 HIGH |
| A flaw was found in samba. Spaces used in a string around a domain name (DN), while supposed to be ignored, can cause invalid DN strings with spaces to instead write a zero-byte into out-of-bounds memory, resulting in a crash. The highest threat from this vulnerability is to system availability. | |||||
| CVE-2020-14342 | 3 Fedoraproject, Opensuse, Samba | 3 Fedora, Leap, Cifs-utils | 2023-11-07 | 4.4 MEDIUM | 7.0 HIGH |
| It was found that cifs-utils' mount.cifs was invoking a shell when requesting the Samba password, which could be used to inject arbitrary commands. An attacker able to invoke mount.cifs with special permission, such as via sudo rules, could use this flaw to escalate their privileges. | |||||
| CVE-2020-14303 | 5 Canonical, Debian, Fedoraproject and 2 more | 5 Ubuntu Linux, Debian Linux, Fedora and 2 more | 2023-11-07 | 5.0 MEDIUM | 7.5 HIGH |
| A flaw was found in the AD DC NBT server in all Samba versions before 4.10.17, before 4.11.11 and before 4.12.4. A samba user could send an empty UDP packet to cause the samba server to crash. | |||||
| CVE-2020-10745 | 4 Debian, Fedoraproject, Opensuse and 1 more | 4 Debian Linux, Fedora, Leap and 1 more | 2023-11-07 | 7.8 HIGH | 7.5 HIGH |
| A flaw was found in all Samba versions before 4.10.17, before 4.11.11 and before 4.12.4 in the way it processed NetBios over TCP/IP. This flaw allows a remote attacker could to cause the Samba server to consume excessive CPU use, resulting in a denial of service. This highest threat from this vulnerability is to system availability. | |||||
| CVE-2020-10730 | 5 Debian, Fedoraproject, Opensuse and 2 more | 5 Debian Linux, Fedora, Leap and 2 more | 2023-11-07 | 4.0 MEDIUM | 6.5 MEDIUM |
| A NULL pointer dereference, or possible use-after-free flaw was found in Samba AD LDAP server in versions before 4.10.17, before 4.11.11 and before 4.12.4. Although some versions of Samba shipped with Red Hat Enterprise Linux do not support Samba in AD mode, the affected code is shipped with the libldb package. This flaw allows an authenticated user to possibly trigger a use-after-free or NULL pointer dereference. The highest threat from this vulnerability is to system availability. | |||||
| CVE-2020-10700 | 3 Fedoraproject, Opensuse, Samba | 3 Fedora, Leap, Samba | 2023-11-07 | 2.6 LOW | 5.3 MEDIUM |
| A use-after-free flaw was found in the way samba AD DC LDAP servers, handled 'Paged Results' control is combined with the 'ASQ' control.
