This is the official release announcement for IPFire 2.17 – Core Update 97. An other OpenSSL security fix has been released, which is shipped in this Core Update among some other security vulnerabilities. As this is a rather urgent update, we recommend to install it as soon as possible. We also recommend rebooting after the update has been installed.

OpenSSL security fixes – 1.0.2f

It is possible to exploit the Diffie-Hellman key exchange (CVE-2016-0701)and get hold of the server’s private exponent. With that any future connections can be decrypted. Please check out the original security advisory for more details.

A second fix (CVE-2015-3197) in the OpenSSL library fixes the deactivation of some SSLv2 ciphers.

An other change will strengthen SSL connections against being taken over by a man-in-the-middle attack that tries to downgrade the length of the Diffie-Hellman key that is being used.

OpenSSH 7.1p2

An information leak (CVE-2016-0777) flaw was found in the way the OpenSSH client roaming feature was implemented. A malicious server could potentially use this flaw to leak portions of memory (possibly including private SSH keys) of a successfully authenticated OpenSSH client.

The SSH daemon will be restarted during the update in case it is enabled.
