OpenBSD Errata: December 1st, 2020 (xmaplen)

Theo Buehler-5
Errata patches for the X server have been released for OpenBSD 6.7 and 6.8.

Multiple input validation failures in the X server XKB extension can lead
to out of bounds memory accesses for authorized clients.

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:
