I. Background pf is an Internet Protocol packet filter originally written for OpenBSD. pf uses a state table to determine whether to allow a packet that is from a known/already open transmission. It identifies ICMPv6 states based on the address family, protocol, addresses, and the ID. Normally, states are created by outgoing packets, or by incoming packets matching 'pass' rules. Packets that do not match any rule will be blocked or allowed depending on the default rule. ICMPv6 Neighbor Discovery has to be allowed in the firewall for IPv6 to work properly in broadcast networks, such as Ethernet. II. Problem Description Patches for a previous security advisory, FreeBSD-SA-24:05, were incomplete and introduced some overly strict pf state tracking for ICMPv6 packets. III. Impact The bugs may prevent ICMPv6 functions, e.g., Neighbor Discovery, from working as designed when the pf firewall is configured. IV. Workaround No workaround is available but systems not using IPv6 and the pf firewall are not affected. V. Solution Upgrade your system to a supported FreeBSD stable or release / security branch (releng) dated after the correction date and reboot. Perform one of the following: 1) To update your system via a binary patch: Systems running a RELEASE version of FreeBSD on the amd64 or arm64 platforms, or the i386 platform on FreeBSD 13, can be updated via the freebsd-update(8) utility: # freebsd-update fetch # freebsd-update install # shutdown -r +10min "Rebooting for a security update" 2) To update your system via a source code patch: The following patches have been verified to apply to the applicable FreeBSD release branches. a) Download the relevant patch from the location below, and verify the detached PGP signature using your PGP utility.
