Jan 4, 2024

CVE-2023-0286 is a high-severity type confusion vulnerability affecting certain versions of OpenSSL, a widely used software library for secure communication. This vulnerability is related to X.400 address processing inside an X.509 GeneralName and may allow an attacker to read memory contents or enact a denial of service. The issue was reported by David Benjamin from Google and fixed by Hugo Landau.

How do I know if I'm affected?

If you're using OpenSSL, you might be affected by this vulnerability. This issue impacts OpenSSL versions 1.0.2 up to 1.0.2zg, 1.1.1 up to 1.1.1t, and 3.0.0 up to 3.0.8. To check if you're affected, verify which version of OpenSSL you're using. If it falls within these ranges, you could be at risk. This vulnerability can allow an attacker to read memory contents or cause a denial of service, particularly in applications that have implemented their own functionality for retrieving CRLs over a network.

What should I do if I'm affected?

If you're affected by this vulnerability, it's important to upgrade your OpenSSL version to a patched one. For OpenSSL 3.0 users, upgrade to 3.0.8; for 1.1.1 users, upgrade to 1.1.1t; and for 1.0.2 users with premium support, upgrade to 1.0.2zg. Upgrading helps protect your system from potential attacks and memory leaks.
