Updating openssl due to security scan Italian sexy chat

Nevertheless, in addition to ensuring that your Postfix configuration disables SSLv2 and weak or obsolete ciphers, you should also deploy the appropriate Open SSL upgrade.

First, it is surprisingly common for services to share keys.

DROWN can target your HTTPS server even if only your email server supports SSLv2, so long as the two share the same private key.

But today’s release fixes a number of other vulnerabilities, and we cannot emphasize the importance of timely upgrades enough.

If you obtained Open SSL directly from us (from https:// or from https://github.com/openssl/openssl), run the following command to find out: If you are using the system Open SSL provided with your Linux distribution, or obtained Open SSL from another vendor, the version number is not a reliable indicator of the security status.

Thus, while the following FAQ will guide you through defending your services against DROWN, we encourage you to upgrade to Open SSL latest even if you’re not vulnerable, and keep doing so regularly upon every security release. You can only be sure that you are not vulnerable if none of your services sharing a given private key enable SSLv2.

Your secure TLS-only HTTPS server is vulnerable if you expose the same key on an email server that supports SSLv2.

Debian users can also track the security status of Debian releases, using Debian’s security tracker. DROWN attacks can only target individual sessions, not the server’s key.

All issues affecting Open SSL can be found in the search by source package and information about DROWN will appear under the tracker for CVE-2016-0800. Even if there has been a successful DROWN attack against you, there is no need to regenerate your private key, so long as you can confidently identify all services that share this key, and disable SSLv2 for them.

The attack works against every known SSL/TLS implementation supporting SSLv2.
