Security Leftovers

  • Looking At The New "Critical" Security Firmware Update Hitting Systems - Delivers New Intel Microcode - Phoronix

    Earlier this week the Linux Vendor Firmware Service began surging with activity following many new system firmware files being uploaded for what appears to be a "high severity upcoming security issue" but currently undisclosed. That issue hasn't been made public yet, but after poking around it is updating the Intel CPU microcode. After that earlier article, Red Hat's Richard Hughes who is the lead LVFS/fwupd lead developer commented that they shipped more than 156,000 firmware updates to end-users in a single day. The day after they were still at around twice their usual volume. For hardware with LVFS support for firmware updates, it's been a busy week but that only covers a small portion of the hardware out there.

    [ Chris Lamb ]
    * If the debian.deb822 module raises any exception on import, re-raise it as
      an ImportError instead. This should fix diffoscope on some Fedora systems.
      Thanks to Mattia Rizzolo for suggesting this particular solution.
      (Closes: reproducible-builds/diffoscope#300)

  • How to use Filters in Wireshark

    Wireshark is a Free and Open Source Software (FOSS) and it is developed by a community of enthusiastic developers. Wireshark (Formerly Ethereal) is used for capturing and investigating the traffic on a network. With Wireshark one can see what is going on their network: You can see from where the traffic is coming in and where it is going to. If you are working in a production environment, you are going to get a lot of traffic. It will be very cumbersome to inspect this traffic without the knowledge of Wiresharks’s filter functionalities.

Tumbleweed Updates From openSUSE People

  • Tools Strace, BusyBox Update in Tumbleweed - openSUSE News

    openSUSE Tumbleweed had a variety of package updates in smaller snapshots throughout this week. A few things being prepared for Tumbleweed is that the Linux Kernel 5.16.1 was scheduled for check in and pre-integration tests for GNU Compiler Collection 12 have been started; the rolling release anticipates a merge of GCC 12 in mid-Spring. The latest Tumbleweed snapshot, 20220117, updated Italian translations for libstorage-ng 4.4.75 and added python-rpm-macros for building the package. Haskell support was dropped in the thrift 0.15.0 package, which is a scalable cross-language service framework for Remote Procedure Call and Inter-Process Communication. No changelogs were provided for the plugins package written in Rust called gstreamer-plugins-rs. The remaining packages in the snapshot were all Python Package Index updates. Among the key PyPI packages to point out is the major version update of python-unicodedata2 14.0.0, which dropped support for End of Life Python 2.7 and 3.5 and added support for Python 3.9, 3.10 and PyPy3. A Tumbleweed arm 20220118 snapshot was release updating the same package listed above.

  • openSUSE Tumbleweed – Review of the week 2022/03

    Dear Tumbleweed users and hackers, 7 days have passed since my last review – and as many snapshots have been released since then too. And this even includes my error of one day performing the check-in ‘slightly too late’ (i.e. past midnight). That’s the reason that 0119 did not exist. The check-in was too late and it was already January 20th by then. The snapshots released were numbered 0113, 0114, 0115, 0116, 0117, 0118, and 0120.
