OpenBSD Errata: December 22nd, 2018 (pcbopts)

Errata patches for the kernel have been released for OpenBSD 6.3 and 6.4.

The setsockopt(2) system call could overflow mbuf cluster kernel memory
by 4 bytes.

Binary updates for the amd64, i386, and arm64 platforms are available
via the syspatch utility. Source code patches can be found on the
respective errata page:

As these affect the kernel, a reboot will be needed after patching.
