Updating openssl

updating openssl-30

Now an attacker who is able to intercept and alter traffic between the systems can screw up the handshake process and make it fail with arbitrary network errors (think: TCP RST).In this case the client often retries the connection with a lower initial SSL/TLS protocol version, say SSLv3 or TLS1, which makes it easier for the bad guy to attack the encrypted channel.

The stable release of Open SSL is updated regularly, and Apple maintains a Mac-specific update through its Software Update System.POODLE relies on SSLv3, but today nearly every server and client supports at least TLS 1.0 in addition to SSLv3, which means SSLv3 connections should (and in fact are) be rather rare.But there is still a threat because of downgrade compatibility between the protocols.[/Update] TLS Fallback Signaling Cipher Suite Value prevents SSL/TLS protocol downgrades a man-in-the-middle can enforce when both sides actually support higher protocol versions.For example, a Client sends a handshake message, and that will be the negotiated SSL/TLS version of the connection.To update Open SSL on a Mac, make sure your computer is up to date, and run the updating utility if it is not. Update either Open SSL or your entire your computer, if required.

If you're updating only Open SSL, click to select all packages except "Open SSL," then click the "Update" menu and choose "Ignore Update." Click "OK" on the confirmation dialog.

Then, if the upgrade is in the v0.12 branch, create a pull request and run the node-accept-pull-request Jenkins job (make sure to tests in parallel.

Due to the large number of tests that need to be run, this tests suite can take a long time to complete.

— UPDATE: A new version is available: Open SSL 1.0.1h (release notes) Enjoy!

Some knowledge of how Open SSL is built and embedded within the node binary and of the existing floating patches is necessary.
