CVE-2022-0778 is a high-severity vulnerability affecting OpenSSL versions 1.0.2, 1.1.1, and 3.0. It involves a bug in the BN\_mod\_sqrt() function that can cause it to loop indefinitely for non-prime moduli, leading to a denial of service attack. This issue impacts a variety of systems, including TLS clients and servers, hosting providers, certificate authorities, and other applications that use the BN\_mod\_sqrt() function where an attacker can control the parameter values.
How do I know if I'm affected?
If you're using OpenSSL versions 1.0.2, 1.1.1, or 3.0, you might be affected by this vulnerability. This issue is related to a bug in the BN\_mod\_sqrt() function that can cause an infinite loop, leading to a denial of service attack. To check if you're affected, you can look for the specific OpenSSL version you're using. Keep in mind that this vulnerability has been fixed in OpenSSL 1.1.1n and 3.0.2.
What should I do if I'm affected?
If you're affected by the CVE-2022-0778 vulnerability, it's important to update your OpenSSL to a fixed version, such as 1.1.1n or 3.0.2. To do this, check for updates from your software provider or operating system, and follow their instructions to upgrade your OpenSSL package. This will help protect your system from potential denial of service attacks.
Is this in CISA’s Known Exploited Vulnerabilities Catalog?
