OpenBSD Errata: August 24th, 2018 (fpufork)

Errata patches for the kernel have been released for OpenBSD 6.3 and 6.2.

State from the FPU of one userland process could be exposed to other
processes.

Binary updates for the amd64 platform are available via the syspatch utility.
Source code patches can be found on the respective errata pages:

  https://www.openbsd.org/errata62.html
  https://www.openbsd.org/errata63.html

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