SB2023041499 - Anolis OS update for nodejs:14 module

Description

This security bulletin contains information about 7 secuirty vulnerabilities.

1) Resource exhaustion (CVE-ID: CVE-2021-35065)

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

The vulnerability exists due to application does not properly control consumption of internal resources when processing regular expressions. A remote attacker can trigger resource exhaustion and perform a regular expression denial of service (ReDoS) attack.

2) Inefficient Algorithmic Complexity (CVE-ID: CVE-2022-25881)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to regular expression denial of service that occurs when the server reads the cache policy from the request using this library. A remote unauthenticated attacker can send malicious request header values to the server and perform a denial of service attack.

3) Incorrect Regular Expression (CVE-ID: CVE-2022-3517)

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

The vulnerability exists due to insufficient input validation when processing regular expressions. A remote attacker can pass specially crafted data to the application and perform regular expression denial of service (ReDos) attack.

4) Input validation error (CVE-ID: CVE-2022-38900)

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

The vulnerability exists due to insufficient validation of user-supplied input. A remote attacker can pass specially crafted input to the application and perform a denial of service (DoS) attack.

5) Buffer overflow (CVE-ID: CVE-2022-4904)

The vulnerability allows a local user to perform a denial of service (DoS) attack.

The vulnerability exists due to a boundary error within the config_sortlist() function. A local user can trigger memory corruption and perform a denial of service (DoS) attack.

6) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2023-23918)

The vulnerability allows a remote user to bypass implemented security restrictions.

The vulnerability exists due to improperly imposed security restrictions within the process.mainModule.require() method. A remote user can access non authorized modules.

7) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2023-23920)

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

The vulnerability exists due to application insecurely loads ICU data through ICU_DATA environment variable with elevated privileges. A remote user can gain access to potentially sensitive information.
