SB2023092669 - Red Hat Enterprise Linux 8.6 Extended Update Support update for the nodejs:16 module

Description

This security bulletin contains information about 8 secuirty vulnerabilities.

1) Incorrect Regular Expression (CVE-ID: CVE-2022-25883)

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 via the new Range function and perform regular expression denial of service (ReDos) attack.

2) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2023-30581)

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

The vulnerability exists due to the use of proto in process.mainModule.proto.require(). This allows to bypass the policy mechanism and require modules outside of the policy.json definition.

3) Input validation error (CVE-ID: CVE-2023-30588)

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

The vulnerability exists due to insufficient validation of user-supplied public key within the crypto.X509Certificate() API. A remote user can pass an invalid public key to the application and perform a denial of service (DoS) attack.

4) Inconsistent interpretation of HTTP requests (CVE-ID: CVE-2023-30589)

The vulnerability allows a remote attacker to perform HTTP request smuggling attacks.

The vulnerability exists due to improper validation of HTTP requests in the llhttp parser. A remote attacker can send a specially crafted HTTP request to the server and smuggle arbitrary HTTP headers.

Successful exploitation of vulnerability may allow an attacker to poison HTTP cache and perform phishing attacks.

5) Inconsistency between implementation and documented design (CVE-ID: CVE-2023-30590)

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

The vulnerability exists due to inconsistency between implementation and documented design within the generateKeys() API function. The documented behavior is different from the actual behavior, and this difference could lead to security issues in applications that use these APIs as the DiffieHellman may be used as the basis for application-level security.

6) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2023-32002)

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

The vulnerability exists due to improperly imposed security restrictions for the Module._load() method. A remote attacker can bypass the policy mechanism and include modules outside of the policy.json definition for a given module.

7) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2023-32006)

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

The vulnerability exists due to improperly imposed security restrictions for the module.constructor.createRequire() method. A remote attacker can bypass the policy mechanism and include modules outside of the policy.json definition for a given module.

8) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2023-32559)

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

The vulnerability exists due to usage of deprecated API process.binding(). A remote attacker can bypass the policy mechanism by requiring internal modules and eventually take advantage of process.binding('spawn_sync') run arbitrary code, outside of the limits defined in a policy.json file.
