SB2022111599 - Multiple vulnerabilities in Node.js

Description

This security bulletin contains information about 3 secuirty vulnerabilities.

1) Buffer overflow (CVE-ID: CVE-2022-3602)

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

The vulnerability exists due to a boundary error when processing the email address field inside  X.509 certificate. A remote attacker can supply a specially crafted certificate to the application, trigger a 4-byte buffer overflow and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system but requires that either a CA signs the malicious certificate or for the application to continue certificate verification despite failure to construct a path to a trusted issuer.

2) Buffer overflow (CVE-ID: CVE-2022-3786)

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

The vulnerability exists due to a boundary error when processing the email address field length inside a X.509 certificate. A remote attacker can supply a specially crafted certificate to the application, trigger a buffer overflow and crash the application.

3) Reliance on Reverse DNS Resolution for a Security-Critical Action (CVE-ID: CVE-2022-43548)

The vulnerability allows a remote attacker to perform DNS rebinding attacks.

The vulnerability exists due to improper validation of octal IP address within the Node.js rebinding protector for --inspec. A remote attacker can resolve the invalid octal address via DNS. When combined with an active --inspect session, such as when using VSCode, an attacker can perform DNS rebinding and execute arbitrary code in client's browser.
