OpenBSD Errata: December 22nd, 2018 (pcbopts)
20 December, 2018 by firstname.lastname@example.org | openbsd
Errata patches for the kernel have been released for OpenBSD 6.3 and 6.4. The setsockopt(2) system call could overflow mbuf cluster kernel memory by 4 bytes. 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/errata63.html https://www.openbsd.org/errata64.html As these affect the kernel, a reboot will be needed after patching.
