CVE-2023-5678 is a medium-severity vulnerability that affects certain versions of OpenSSL. It involves generating or checking excessively long X9.42 DH keys or parameters, which can result in slow performance and potentially lead to a Denial of Service (DoS) attack. Systems using the impacted versions of OpenSSL are vulnerable to this issue, making it crucial for users to update their software to a secure version.

How do I know if I'm affected?

To determine if you're affected by the vulnerability, you'll need to check the version of OpenSSL you're using. The affected versions are as follows:

  • 1.0.2 up to (excluding) 1.0.2zj

  • 1.1.1 up to (excluding) 1.1.1x

  • 3.0.0 up to (excluding) 3.0.13

  • 3.1.0 up to (excluding) 3.1.5

If your OpenSSL version falls within these ranges, your system may be vulnerable to this issue, which involves generating or checking excessively long X9.42 DH keys or parameters, potentially leading to slow performance and denial of service attacks.

What should I do if I'm affected?

If you're affected by the vulnerability, it's important to update your OpenSSL software to a secure version. To do this, follow these simple steps:

  1. Identify your current OpenSSL version.

  2. Check if it falls within the affected version ranges.

  3. Update to a secure version (1.0.2zj, 1.1.1x, 3.0.13, or 3.1.5).

By updating your OpenSSL software, you'll protect your system from potential slow performance and denial of service attacks.
