  • OpenBSD Errata: July 25th, 2019 (tcpsack)

    From T.J. Townsend@21:1/5 to All on Wed Jul 24 15:30:02 2019
    Errata patches for the kernel have been released for OpenBSD 6.4 and 6.5.

    By creating long chains of TCP SACK holes, an attacker could possibly
    slow down the system temporarily.

    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/errata64.html
    https://www.openbsd.org/errata65.html

    As these affect the kernel, a reboot will be needed after patching.
