This release ships a large number of microcode updates for various
processors (linux-firmware
30.7.2018, intel-microcode 20180807). Most notable, vulnerabilities in
Intel processors might
have been fixed or mitigations applied. Microcodes are now also being
loaded into the processor
earlier to avoid any attacks on the system at boot time.
This update also comes with a large number of smaller changes that
improve security and fix bugs:
* OpenSSL has been updated to versions 1.1.0i and for legacy
applications version 1.0.2p
(CVE-2018-0732 and CVE-2018-0737)
* IPsec
* IPsec now supports ChaCha20/Poly1305 for encryption
* It also allows to configure a connection to passively wait until a
peer initiates it. This
is helpful in some environments where one peer is behind NAT.
* OpenVPN
* Creating Diffie-Hellman keys with length of 1024 bits is no
longer possible because they
are considered insecure and not being supported by OpenVPN any
more
* There is better warnings about this and other cryptographic
issues on the web user interface
* Intrusion Detection
* Links in the log files have been fixed to open the correct page
with details about
a certain attack
* Downloads of rulesets properly validate any TLS certificates
* The /proc filesystem has been hardened so that no kernel pointers
are being exposed any more
* nss-myhostname is now being used to dynamically determine the
hostname of the IPFire
system. Before /etc/hosts was changed which is no longer required.
* collectd: The cpufreq plugin has been fixed
* Generating a backup ISO file has been fixed
* Updated packages: apache 2.4.34, conntrack-tools 1.4.5, coreutils
8.29, fireinfo,
