Security Bulletin

This security bulletin contains information about 10 vulnerabilities.

1) Out-of-bounds read

EUVDB-ID: #VU78577

Risk: Medium

CVSSv4.0: 2.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2022-2127

CWE-ID: CWE-125 - Out-of-bounds read

Exploit availability: No

Description

The vulnerability allows a remote attacker to gain access to sensitive information or perform denial of service (DoS) attack.

The vulnerability exists due to a boundary condition in winbindd_pam_auth_crap.c in winbind AUTH_CRAP when performing NTLM authentication. A remote attacker can trigger an out-of-bounds read error and gain access to sensitive information or crash the server.

Mitigation

6) Improper Authorization

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

Description

The 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.

Mitigation

Install updates from vendor's repository.

7) Permissions, Privileges, and Access Controls

EUVDB-ID: #VU81872

Risk: Low

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

Description

The 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".

Mitigation

Install updates from vendor's repository.

Description

The vulnerability allows a remote user to gain access to potentially sensitive information.

The vulnerability exists due to a design error in Samba's implementation of the DirSync control, which can allow replication of critical domain passwords and secrets by Active Directory accounts authorized to do some replication, but not to replicate sensitive attributes. A remote user can obtain sensitive information from the AD DC and compromise the Active Directory.

Mitigation

Install updates from vendor's repository.

9) Resource management error

EUVDB-ID: #VU81871

Risk: Medium

CVSSv4.0: 4.9 [CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2023-42669

CWE-ID: CWE-399 - Resource Management Errors

Exploit availability: No

Description

The 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.

Mitigation

Install updates from vendor's repository.

EUVDB-ID: #VU81867

Risk: Medium

CVSSv4.0: 4.9 [CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2023-42670

CWE-ID: CWE-399 - Resource Management Errors

Exploit availability: No

Description

The 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.

Mitigation

Install updates from vendor's repository.
