Description

This security bulletin contains information about 6 vulnerabilities.


1) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2020-25720)

CWE-ID: CWE-264 - Permissions, Privileges, and Access Controls

CVSSv4: CVSS:4.0/AV:A/AC:L/AT:N/PR:L/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a local user to escalate privileges within the network.

The vulnerability exists due to create child permissions allows full write access to all attributes. A local user can escalate privileges within the network.


2) Out-of-bounds read (CVE-ID: CVE-2022-2127)

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

CVSSv4: 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


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.


3) Security features bypass (CVE-ID: CVE-2023-3347)

CWE-ID: CWE-254 - Security Features

CVSSv4: CVSS:4.0/AV:A/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote attacker to gain access to sensitive information.

The vulnerability exists due to SMB2 packet signing feature is not enforced if the server is configured with the "server signing = required" option or for SMB2 connections to Domain Controllers where SMB2 packet signing is mandatory. A remote attacker can intercept and manipulate data.


4) Infinite loop (CVE-ID: CVE-2023-34966)

CWE-ID: CWE-835 - Loop with Unreachable Exit Condition ('Infinite Loop')

CVSSv4: CVSS:4.0/AV:A/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to infinite loop when parsing Spotlight mdssvc RPC packets. A remote attacker can consume all available system resources and cause denial of service conditions on servers where Spotlight is explicitly enabled globally or on individual shares with "spotlight = yes".


5) Type Confusion (CVE-ID: CVE-2023-34967)

CWE-ID: CWE-843 - Type confusion

CVSSv4: CVSS:4.0/AV:A/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to a type confusion error when parsing Spotlight mdssvc RPC packets. A remote attacker can send specially crafted data to the server, trigger a type confusion error and crash the server.


6) Information disclosure (CVE-ID: CVE-2023-34968)

CWE-ID: CWE-200 - Exposure of sensitive information to an unauthorized actor

CVSSv4: CVSS:4.0/AV:A/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear


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

The vulnerability exists due to excessive data output by the application. A remote attacker can send a specially crafted RPC request to the server and obtain real server-side share path.
