OpenBSD Errata: April 21st, 2018 (gif)
21 April, 2018 by firstname.lastname@example.org | openbsd
Errata patches for the generic tunnel interface driver have been released for OpenBSD 6.3. In the gif(4) interface, use the specified protocol for IPv6, plug an mbuf leak, and avoid a use after free. Binary updates for the amd64, i386, and arm64 platforms are available via the syspatch utility. Source code patches can be found on the errata page: https://www.openbsd.org/errata63.html As this affects the kernel, a reboot will be needed after patching.
