Security Bulletin
This security bulletin contains information about 4 vulnerabilities.
EUVDB-ID: #VU81875
Risk: High
CVSSv4.0: 8 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N/E:U/U:Amber]
CVE-ID: CVE-2023-3961
CWE-ID:
CWE-285 - Improper Authorization
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to compromise the affected system.
The vulnerability exists due to improper input validation when handling client pipe names. A remote attacker can provide a specially crafted pipe name containing directory traversal characters and force Samba to connect to Unix domain sockets outside of the private directory meant to restrict the services a client could connect to.The connection to Unix domain sockets is performed as root, which means that if client sends a pipe name that resolved to an external service using an existing Unix
domain socket, the client is able to connect to it without
any filesystem restrictions.
Install updates from vendor's repository.

CVSSv4.0: 1.3 [CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear]
CVE-ID: CVE-2023-4091
CWE-ID:
CWE-264 - Permissions, Privileges, and Access Controls
Exploit availability: No
DescriptionThe vulnerability allows a remote user to truncate read-only files.
The vulnerability exists due to an error in the way SMB protocol implementation in Samba handles file operations. A remote user can request read-only access to files and then truncate them to 0 bytes by opening files with OVERWRITE disposition when using the acl_xattr Samba VFS module with the smb.conf setting "acl_xattr:ignore system acls = yes".

CVE-ID: CVE-2023-42669
CWE-ID:
CWE-399 - Resource Management Errors
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to inclusion of the "rpcecho" server into production build, which can call sleep() on AD DC. A remote user can request the server block using the "rpcecho" server and perform a denial of service (DoS) attack.

CVE-ID: CVE-2023-42670
CWE-ID:
CWE-399 - Resource Management Errors
Exploit availability: No
DescriptionThe vulnerability allows a remote user to perform a denial of service (DoS) attack.
The vulnerability exists due to improper management of internal resources within the application when Samba RPC server is under load, which can lead to incorrect start of servers not built for the AD DC. A remote user can cause a high load to Samba RPC server and perform a denial of service (DoS) attack.
