• OpenBSD Errata: May 19th, 2017 (exec_subr)

    From T.J. Townsend@21:1/5 to All on Wed May 24 08:30:01 2017
    Errata patches for exec_subr have been released for OpenBSD 6.1 and 6.0.

    An additional mitigation is added by placing a gap of 1 MB between the
    stack and mmap spaces.

    Binary updates for the amd64 and i386 platforms are available via the
    syspatch utility. Source code patches can be found on the respective
    errata pages:

    https://www.openbsd.org/errata60.html
    https://www.openbsd.org/errata61.html

    As this affects the kernel, a reboot will be needed after patching.
