A critical vulnerability nicknamed \u201cHeartbleed\u201d was discovered in OpenSSL, the most popular SSL module used on Linux \/ cPanel servers. This exploit allows a third party to steal information that would otherwise be secured and encrypted with the SSL\/TLS protocol, and to steal the private keys from the certificate pair itself.<\/p>\n

Here\u2019s a great site where you can learn more about the vulnerability: heartbleed.com<\/p>\n

We\u2019ve implemented updates in all areas where our systems were using affected versions of OpenSSL, and we are following best practices. We have also re-keyed all certificates on our web servers.<\/p>\n

Important Facts<\/h2>\n
    \n
  1. This is not a vulnerability with SSL\/TLS or SSLs.com.<\/li>\n
  2. SSL\/TLS is not broken, nor are the digital certificates issued by Comodo (now Sectigo<\/a>) through SSLs.com.<\/li>\n
  3. Users of OpenSSL versions 1.0.1 through 1.0.1f with the heartbeat extension enabled are affected.<\/li>\n
  4. OpenSSL version 1.0.1g addresses the vulnerability, as well as OpenSSL instances compiled without the heartbeat extension.<\/li>\n<\/ol>\n

    How does this impact SSLs.com customers?<\/h2>\n

    First of all, if you are not using OpenSSL on your servers, you are not affected.<\/p>\n

    If you do use OpenSSL, we strongly advise the following:<\/p>\n

      \n
    1. Identify which servers are running OpenSSL (versions 1.0.1 through 1.0.1f are<\/strong> affected).<\/li>\n
    2. Update to the latest patched version of the software (1.1.1b), or recompile OpenSSL without the heartbeat extension, if applicable.<\/li>\n
    3. Reissue any SSL certificates on affected web servers after moving to a patched version of OpenSSL.<\/li>\n
    4. Test your SSL installations:\u00a0https:\/\/www.ssllabs.com\/ssltest\/<\/a><\/li>\n
    5. Revoke any certificates that were replaced. Please revoke AFTER the reissue has been completed and you have successfully installed<\/strong>\u00a0the new certificate on your web server(s).<\/li>\n
    6. Consider resetting end-user passwords that may have been visible in a compromised server memory.<\/li>\n<\/ol>\n

      How to Reissue and Revoke Certificates at SSLs.com<\/h2>\n

      Reissue is performed from within your SSLs.com<\/a> account and is free of charge. More information on how to reissue an SSL certificate can be found here<\/a>.<\/p>\n

      Revocation Procedure<\/h3>\n

      Once the certificate is reissued and successfully installed, the original certificate (the one that could be compromised) must be revoked, so that attackers can\u2019t use it to impersonate you.<\/p>\n

      In order to have any Comodo<\/strong> (now Sectigo<\/a>) certificate reissued, please contact us<\/a> with a revocation request.<\/p>\n","protected":false},"excerpt":{"rendered":"
