Dec 18, 2023

CVE-2022-3602 is a high-severity buffer overrun vulnerability affecting OpenSSL versions 3.0.0 to 3.0.6. It occurs in X.509 certificate verification, specifically in name constraint checking, and can be triggered by a malicious email address. This vulnerability could result in a crash (causing a denial of service) or potentially remote code execution, although many platforms implement stack overflow protections that can mitigate the risk. Users are encouraged to upgrade to OpenSSL 3.0.7 to address this issue. The vulnerability affects a wide range of systems that use OpenSSL for secure communication.

How do I know if I'm affected by CVE-2022-3602?

If you're using OpenSSL versions 3.0.0 to 3.0.6, you might be affected by the CVE-2022-3602 vulnerability. This issue is related to a buffer overrun in X.509 certificate verification, specifically in name constraint checking. An attacker can trigger this vulnerability by crafting a malicious email address, which could lead to a crash (denial of service) or potentially remote code execution. However, many platforms have stack overflow protections that can help mitigate the risk.

What should I do if I'm affected by CVE-2022-3602?

If you're affected by the CVE-2022-3602 vulnerability, it's important to take action to protect your system. To do this, simply upgrade to OpenSSL 3.0.7 if you're using OpenSSL 3.0. Users of OpenSSL 1.1.1 and 1.0.2 are not affected and don't need to take any action. Upgrading will help prevent potential crashes or remote code execution risks.
