    Time Event
    2:33p
    Security updates for Wednesday
    Security updates have been issued by Arch Linux (dbus, firefox, kernel, linux-lts, linux-zen, and python), CentOS (bind and kernel), Debian (firefox-esr, glib2.0, and vim), Fedora (dbus, kernel, kernel-headers, mingw-libxslt, poppler, and python-gnupg), openSUSE (gnome-shell, kernel, libcroco, php7, postgresql10, python, sssd, and thunderbird), Oracle (kernel and libvirt), Red Hat (go-toolset:rhel8, gvfs, java-11-openjdk, pki-deps:10.6, systemd, and WALinuxAgent), SUSE (docker, kernel, libvirt, openssl, openssl1, and python-Jinja2), and Ubuntu (samba).
    2:42p
    Stable kernel updates
    Stable kernels 5.1.12, 4.19.53, and 4.14.128 have been released. They all contain
    important fixes and users should upgrade.
    5:10p
    [$] More frequent Python releases?
    Python has followed an 18-month release cycle for many years now; each
    new 3.x release comes at that frequency. It has worked well, overall,
    but there is interest in having a shorter cycle, which would mean that new
    features get into users' hands more quickly. But changing that longstanding
    cycle has implications in many different places, some of which have come up
    as part of a discussion on switching to a cycle of a different length.
    9:12p
    Alpine Linux 3.10.0 released
    Version
    3.10.0     of the Alpine Linux distribution is out. It includes a switch
    to the iwd WiFi management daemon, support
    for the ceph filesystem, the lightdm display manager, and more.
    9:14p
    Ubuntu dropping i386 support
    Starting with the upcoming "Eoan Ermine" (a.k.a. 19.10) release, the Ubuntu
    distribution will
    not support 32-bit x86 systems    . "The Ubuntu engineering team has
    reviewed the facts before us and concluded that we should not continue to
    carry i386 forward as an architecture. Consequently, i386 will not be
    included as an architecture for the 19.10 release, and we will shortly
    begin the process of disabling it for the eoan series across Ubuntu
    infrastructure.    "
    9:24p
    [$] The TCP SACK panic
    Selective
    acknowledgment     (SACK) is a technique used by TCP to help alleviate
    congestion
    that can arise due to the retransmission of dropped packets. It allows
    the endpoints to describe which pieces of the data they have received,
    so that only the missing pieces need to be retransmitted. However, a bug
    was recently found in the Linux implementation of SACK that allows remote
    attackers to panic the system by sending crafted SACK information.
