The next Core Update with number 109 has been released for testing. It comes with a number of package updates which include security fixes and bug fixes all across the place.

DNS Fixes

The DNS proxy which is working inside IPFire has been updated to unbound 1.6.0 which brings various bug fixes. Therefore, QNAME minimisation and hardening below NX domains have been re-activated.

At start time, IPFire now also checks if a router in front of IPFire drops DNS responses which are longer than a certain threshold (some Cisco devices do this to “harden” DNS). If this is detected, the EDNS buffer size if reduced which makes unbound fall back to TCP for larger responses. This might slow down DNS slightly, but keeps it working after all in those misconfigured environments.


  • openssl has been updated to 1.0.2k which fixes a number of security vulnerabilities with “moderate” severity
  • The kernel is now supporting some newer eMMC modules
  • The backup script is now working more reliably on all architectures

  • Furthermore, libpng has been updated to 1.2.57 which fixes some security vulnerabilities
