CRITICALITY: 7.5 HIGH

OVERVIEW: CVE-2002-0657 is a critical vulnerability in OpenSSL versions 0.9.7-beta1 and 0.9.7-beta2. This vulnerability allows remote attackers with Kerberos enabled to execute arbitrary code on affected systems via a buffer overflow in the handling of long master keys.

SOLUTION/MITIGATION: 

The recommended solution to mitigate this vulnerability is to upgrade to a non-vulnerable version of OpenSSL. You can find the latest version and download instructions on the OpenSSL website: https://www.openssl.org/source/.

Here are the specific steps to take:

1. Identify the version of OpenSSL currently in use: This information can often be found in system documentation, server logs, or by running the openssl version command.
2. Verify if your version is vulnerable: Check the list of known affected software configurations in the NVD report for CVE-2002-0657: https://nvd.nist.gov/vuln/detail/CVE-2002-0657
   

Download and install the latest non-vulnerable version of OpenSSL: Follow the instructions provided on the OpenSSL website.

Restart any services that rely on OpenSSL: This ensures that the changes take effect.

Confirmation & Additional Information:

• It is important to test the updated version of OpenSSL thoroughly before deploying it to a production environment.
• If you are unable to upgrade to a non-vulnerable version of OpenSSL immediately, consider disabling Kerberos authentication to mitigate the risk. However, this is not a long-term solution as Kerberos is a widely used security protocol.
• Keep your systems and software up to date with the latest security patches to minimize the risk of exploitation.
