OpenBSD Errata: May 13th, 2020 (wscons)

Errata patches for wscons have been released for OpenBSD 6.5, 6.6,
and 6.7.

An out-of-bounds index access in wscons(4) can cause a kernel crash.

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:

  https://www.openbsd.org/errata65.html
  https://www.openbsd.org/errata66.html
  https://www.openbsd.org/errata67.html

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