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-2022-27239 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-2023-5568 1 Samba 1 Samba 2023-11-24 N/A 6.5 MEDIUM
A heap-based Buffer Overflow flaw was discovered in Samba. It could allow a remote, authenticated attacker to exploit this vulnerability to cause a denial of service.
CVE-2023-42670 2 Fedoraproject, Samba 2 Fedora, Samba 2023-11-24 N/A 6.5 MEDIUM
A flaw was found in Samba. It is susceptible to a vulnerability where multiple incompatible RPC listeners can be initiated, causing disruptions in the AD DC service. When Samba's RPC server experiences a high load or unresponsiveness, servers intended for non-AD DC purposes (for example, NT4-emulation "classic DCs") can erroneously start and compete for the same unix domain sockets. This issue leads to partial query responses from the AD DC, causing issues such as "The procedure number is out of range" when using tools like Active Directory Users. This flaw allows an attacker to disrupt AD DC services.
CVE-2023-42669 2 Redhat, Samba 8 Enterprise Linux, Enterprise Linux Eus, Enterprise Linux For Ibm Z Systems and 5 more 2023-11-24 N/A 6.5 MEDIUM
A vulnerability was found in Samba's "rpcecho" development server, a non-Windows RPC server used to test Samba's DCE/RPC stack elements. This vulnerability stems from an RPC function that can be blocked indefinitely. The issue arises because the "rpcecho" service operates with only one worker in the main RPC task, allowing calls to the "rpcecho" server to be blocked for a specified time, causing service disruptions. This disruption is triggered by a "sleep()" call in the "dcesrv_echo_TestSleep()" function under specific conditions. Authenticated users or attackers can exploit this vulnerability to make calls to the "rpcecho" server, requesting it to block for a specified duration, effectively disrupting most services and leading to a complete denial of service on the AD DC. The DoS affects all other services as "rpcecho" runs in the main RPC task.
CVE-2023-0922 1 Samba 1 Samba 2023-11-07 N/A 5.9 MEDIUM
The Samba AD DC administration tool, when operating against a remote LDAP server, will by default send new or reset passwords over a signed-only connection.
CVE-2023-0614 1 Samba 1 Samba 2023-11-07 N/A 6.5 MEDIUM
The fix in 4.6.16, 4.7.9, 4.8.4 and 4.9.7 for CVE-2018-10919 Confidential attribute disclosure vi LDAP filters was insufficient and an attacker may be able to obtain confidential BitLocker recovery keys from a Samba AD DC.
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-2022-32743 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-2022-29154 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-2021-44142 6 Canonical, Debian, Fedoraproject and 3 more 23 Ubuntu Linux, Debian Linux, Fedora and 20 more 2023-11-07 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-2021-3671 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-2021-20277 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-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-2021-20208 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-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-2020-10760 4 Canonical, Fedoraproject, Opensuse and 1 more 4 Ubuntu Linux, Fedora, Leap and 1 more 2023-11-07 4.0 MEDIUM 6.5 MEDIUM
A use-after-free flaw was found in all samba LDAP server versions before 4.10.17, before 4.11.11, before 4.12.4 used in a AC DC configuration. A Samba LDAP user could use this flaw to crash samba.
