Errata patches for perl have been released for OpenBSD 6.1, 6.2, and 6.3. Heap overflows exist in perl which can lead to segmentation faults, crashes, and reading memory past the buffer.
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 pages: https://www.openbsd.org/errata61.html https://www.openbsd.org/errata62.html https://www.openbsd.org/errata63.html
