Using FreeBSD's pkg-audit, 20 year old bug that went to Mars, FreeBSD on Slimbook, LLDB FreeBSD kernel core dump support, Steam on OpenBSD, Cool but obscure X11 tools, and more NOTES This episode of BSDNow is brought to you by Tarsnap (https://www.tarsnap.com/bsdnow) and the BSDNow Patreon (https://www.patreon.com/bsdnow) Headlines Using FreeBSD's pkg-audit (https://klarasystems.com/articles/using-freebsds-pkg-audit-to-investigate-known-security-issues/) The 20 year old bug that went to Mars (http://blog.securitymouse.com/2014/06/raising-lazarus-20-year-old-bug-that.html) It's rare that you come across a bug so subtle that it can last for two decades. But, that's exactly what has happened with the Lempel-Ziv-Oberhumer (LZO) algorithm. Initially written in 1994, Markus Oberhumer designed a sophisticated and extremely efficient compression algorithm so elegant and well architected that it outperforms zlib and bzip by four or five times their decompression speed. I was impressed to find out that his LZO algorithm has gone to the planet Mars on NASA devices multiple times! Most recently, LZO has touched down on the red planet within the Mars Curiosity Rover, which just celebrated its first martian anniversary on Tuesday. In the past few years, LZO has gained traction in file systems as well. LZO can be used in the Linux kernel within btrfs, squashfs, jffs2, and ubifs. A recent variant of the algorithm, LZ4, is used for compression in ZFS for Solaris, Illumos, and FreeBSD. With its popularity increasing, Lempel-Ziv-Oberhumer has been rewritten by many engineering firms for both closed and open systems. These rewrites, however, have always been based on Oberhumer's core open source implementation. As a result, they all inherited a subtle integer overflow. Even LZ4 has the same exact bug, but changed very slightly. Because the LZO algorithm is considered a library function, each specific implementation must be evaluated for risk, regardless of whether the algorithm used has been patched. Why? We are talking about code that has existed in the wild for two decades. The scope of this algorithm touches everything from embedded microcontrollers on the Mars Rover, mainframe operating systems, modern day desktops, and mobile phones. Engineers that have used LZO must evaluate the use case to identify whether or not the implementation is vulnerable, and in what format.

Am 12. September 2019 hat das Unternehmertreffen Nordwest das erste Mal Halt in Oldenburg gemacht. Gastgeber war die LzO. Jürgen Brüna und Andreas Quelle haben das Netzwerktreffen moderiert. Warum macht ein solches Netzwerktreffen für einen Reha-Manager Sinn? Netzwerken mit Unternehmern hilft Unfallopfern, wieder beruflich Fuß zu fassen. Und bestehende Kontakte können reaktiviert werden. Ganz konkret hat Jörg Dommershausen mit Christine Thümler, die mit Zeitfrei-Dienstleistungen und haushaltsnahen Dienstleistungen hilft, gesprochen. Oder Daniela Vorwerk von AdA Akademie der Ausbilder in Oldenburg. Daniela Vorwerk hilft bei der beruflichen Weiterbildung und Eingliederung. Nicht zu vergessen ist Marlene Marks von der Kids-Förderung Rhauderfehn. Marlene Marks hilft Kindern und Jugendlichen, die Schule leichter und mit Spaß zu schaffen. Das nächste Treffen für Unternehmerinnen und Unternehmer in Oldenburg findet am 10. Oktober 2019 um 18.00 Uhr in der LzO statt

Podcast 5 – Zielone biuroCo kryje się pod hasłem „zielonego biura”? Nie do końca chodzi o ekologię, a bardziej o środowisko… miejsca pracy. To jak się czujemy w biurze, czym oddychamy i jaka panuje atmosfera bardzo wpływa na naszą efektywność. Dzisiaj przewietrzymy, ustawimy odpowiednią temperaturę i dobierzemy najlepszy dla nas sprzęt w biurze marzeń. A wszystko to w oparciu o trendy w zarządzaniu nieruchomościami.Pytania, na które znajdziesz odpowiedzi:• Ile procent czasu spędzamy w biurze i jaki ma to wpływ na nas? • Co oznacza “zielone biuro”?• Jak zadbać o komfort i zdrowie eliminując LZO?• Jak temperatura, oświetlenie wpływa na samopoczucie oraz efektywność pracownika?• Co mówią o biurze certyfikaty BREEAM, LEED oraz WELL?• Czy o zielony certyfikat można się starać wyłącznie na etapie projektowania biura, czy w już istniejącym?• Jak dbać o biuro z certyfikatem?Swoją wiedzą dzielą się Jonathan Cohen, Senior Partner, Dyrektor w Dziale Doradztwa Budowlanego oraz Andrzej Gutowski, Associate Director w Dziale Doradztwa Budowlanego Colliers International.

It's our 50th episode, and we're going to show you how to protect your internet traffic with a BSD-based VPN. We'll also be talking to Robert Watson, of the FreeBSD core team, about security research, exploit mitigation and a whole lot more. The latest news and answers to all of your emails, on BSD Now - the place to B.. SD. This episode was brought to you by Headlines MeetBSD 2014 is approaching (http://www.ixsystems.com/whats-new/ixsystems-to-host-meetbsd-california-2014-at-western-digital-in-san-jose/) The MeetBSD conference is coming up, and will be held on November 1st and 2nd in San Jose, California MeetBSD has an "unconference" format, which means there will be both planned talks and community events All the extra details will be on their site (https://www.meetbsd.com/) soon It also has hotels and various other bits of useful information - hopefully with more info on the talks to come Of course, EuroBSDCon is coming up before then *** First experiences with OpenBSD (https://www.azabani.com/2014/08/09/first-experiences-with-openbsd.html) A new blog post that leads off with "tired of the sluggishness of Windows on my laptop and interested in experimenting with a Unix-like that I haven't tried before" The author read the famous "BSD for Linux users (http://www.over-yonder.net/~fullermd/rants/bsd4linux/01)" series (that most of us have surely seen) and decided to give BSD a try He details his different OS and distro history, concluding with how he "eventually became annoyed at the poor quality of Linux userland software" From there, it talks about how he used the OpenBSD USB image and got a fully-working system He especially liked the simplicity of OpenBSD's "hostname.if" system for network configuration Finally, he gets Xorg working and imports all his usual configuration files - seems to be a happy new user! *** NetBSD rump kernels on bare metal (and Kansai OSC report) (https://blog.netbsd.org/tnf/entry/an_internet_ready_os_from) When you're developing a new OS or a very specialized custom solution, working drivers become one of the hardest things to get right However, NetBSD's rump kernels - a very unique concept - make this process a lot easier This blog post talks about the process of starting with just a rump kernel and expanding into an internet-ready system in just a week Also have a look back at episode 8 (http://www.bsdnow.tv/episodes/2013_10_23-a_brief_intorduction) for our interview about rump kernels and what exactly they do While on the topic of NetBSD, there were also a couple of very detailed reports (http://mail-index.netbsd.org/netbsd-advocacy/2014/08/09/msg000658.html) (with lots of pictures!) of the various NetBSD-themed booths at the 2014 Kansai Open Source Conference (http://d.hatena.ne.jp/mizuno-as/20140806/1407307913) that we wanted to highlight *** OpenSSL and LibreSSL updates (https://www.openssl.org/news/secadv_20140806.txt) OpenSSL pushed out a few new versions, fixing multiple vulnerabilities (nine to be precise!) Security concerns include leaking memory, possible denial of service, crashing clients, memory exhaustion, TLS downgrades and more LibreSSL released a new version (http://marc.info/?l=openbsd-tech&m=140752295222929&w=2) to address most of the vulnerabilities, but wasn't affected by some of them Whichever version of whatever SSL you use, make sure it's patched for these issues DragonFly and OpenBSD are patched as of the time of this recording but, even after a week, NetBSD and FreeBSD are not (outside of -CURRENT) *** Interview - Robert Watson - rwatson@freebsd.org (mailto:rwatson@freebsd.org) FreeBSD architecture, security research techniques, exploit mitigation Tutorial Protecting traffic with a BSD-based VPN (http://www.bsdnow.tv/tutorials/openvpn) News Roundup A FreeBSD-based CGit server (https://lechindianer.de/blog/2014/08/06/freebsd-cgit/) If you use git (like a certain host of this show) then you've probably considered setting up your own server This article takes you through the process of setting up a jailed git server, complete with a fancy web frontend It even shows you how to set up multiple repos with key-based user separation and other cool things The author of the post is also a listener of the show, thanks for sending it in! *** Backup devices for small businesses (http://www.smallbusinesscomputing.com/biztools/6-data-backup-devices-for-small-businesses.html) In this article, different methods of data storage and backup are compared After weighing the various options, the author comes to an obvious conclusion: FreeNAS is the answer He praises FreeNAS and the FreeNAS Mini for their tight integration, rock solid FreeBSD base and the great ZFS featureset that it offers It also goes over some of the hardware specifics in the FreeNAS Mini *** A new Xenocara interview (http://blog.bronevichok.ru/2014/08/06/testing-of-xorg.html) As a follow up to last week's OpenSMTPD interview, this Russian blog interviews Matthieu Herrb about Xenocara If you're not familiar with Xenocara, it's OpenBSD's version of Xorg with some custom patches In this interview, he discusses how large and complex the upstream X11 development is, how different components are worked on by different people, how they test code (including a new framework) and security auditing Matthieu is both a developer of upstream Xorg and an OpenBSD developer, so it's natural for him to do a lot of the maintainership work there *** Building a high performance FreeBSD samba server (https://not.burntout.org/blog/high_performance_samba_server_on_freebsd/) If you've got to PXE boot several hundred Windows boxes to upgrade from XP to 7, what's the best solution? FreeBSD, ZFS and Samba obviously! The master image and related files clock in at over 20GB, and will be accessed at the same time by all of those clients This article documents that process, highlighting some specific configuration tweaks to maximize performance (including NIC bonding) It doesn't even require the newest or best hardware with the right changes, pretty cool *** Feedback/Questions An interesting Reddit thread (http://www.reddit.com/r/BSD/comments/2ctlt4/switched_from_arch_linux_to_openbsd_reference/) (or two (http://www.reddit.com/r/BSD/comments/2dcig9/thinking_about_coming_to_bsd_from_arch)) PB writes in (http://slexy.org/view/s21t7L5bqO) Sean writes in (http://slexy.org/view/s20MFywDqZ) Steve writes in (http://slexy.org/view/s2Td6nq11J) Lachlan writes in (http://slexy.org/view/s215MlpJYV) Justin writes in (http://slexy.org/view/s2N4JKkoKt) ***
