pfSense® software version 2.2.2 release is now available, bringing a number of bug fixes and a couple low-risk security updates that don’t apply to most users.
This release includes two low-risk security updates.
- FreeBSD-SA-15:09.ipv6: Denial of Service with IPv6 Router Advertisements. Where a system is using DHCPv6 WAN type, devices on the same broadcast domain as that WAN can send crafted packets causing the system to lose IPv6 Internet connectivity.
- FreeBSD-SA-15:06.openssl: Multiple OpenSSL vulnerabilities. Most aren’t applicable, and worst impact is denial of service.
Bug Fixes and Change List
As always, you can upgrade from any previous version straight to 2.2.2. For those already running any 2.2x version, this is a low risk upgrade. This is a high priority upgrade for those using IPsec on 2.2x versions. For those on 2.1.x or earlier versions, there are a number of significant changes which may impact you. Pay close attention to the 2.2 Upgrade Notes for the details.
pfSense CE software is Open Source
For those who wish to review the source code in full detail, the changes are all publicly available in three repositories on GitHub:
- Main repository - the web GUI, back end configuration code, and build tools.
- FreeBSD source - the source code, with patches of the FreeBSD base.
- FreeBSD ports - the FreeBSD ports used.
Using the automatic update process is typically easier than reinstalling to upgrade. See the Upgrade Guide page for details.
