OpenBSD Errata: November 16th, 2019 (ifioctl)

16 November, 2019 by tj@openbsd.org | openbsd

Errata patches for the kernel have been released for OpenBSD 6.5 and 6.6.

A regular user could change some network interface parameters due to
missing checks in the ioctl(2) system call.

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

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