draklive 0.3

Filed under

Here comes a new draklive release, it's been a long time since the previous pre-2007.0 release. Developping Mandriva Flash required some new features, but also helped to stabilize my (precious) live creation tool.

There has been a bunch of changes, to sum up:

  • easier to create CD-Rom/USB boot images for live systems

  • easier to create 32 bits live systems from x86_64 host
  • improve writable loopbacks reliability on USB devices, by doing an early fsck check from initrd

CVE-2016-5195 Patched

  • Linux Kernels 4.8.3, 4.7.9 & 4.4.26 LTS Out to Patch "Dirty COW" Security Flaw
    Today, October 20, 2016, Linux kernel maintainer Greg Kroah-Hartman announced three new maintenance updates for the Linux 4.8, 4.7, and 4.4 LTS kernel series, patching a major security vulnerability. Known as "Dirty COW," the Linux kernel vulnerability documented at CVE-2016-5195 is, in fact, a nasty bug that could have allowed local users to write to any file they can read. The worst part is that the security flaw was present in various Linux kernel builds since at least the Linux 2.6.x series, which reached end of life in February this year.
  • Canonical Patches Ancient "Dirty COW" Kernel Bug in All Supported Ubuntu OSes
    As reported earlier, three new Linux kernel maintenance releases arrived for various Linux-based operating systems, patching a critical and ancient bug popularly known as "Dirty COW." We already told you that the kernel vulnerability could be used by a local attacker to run programs as an administrator, and it looks like it also affects all supported Ubuntu releases, including Ubuntu 16.10 (Yakkety Yak), Ubuntu 16.04 LTS (Xenial Xerus), Ubuntu 14.04 LTS (Trusty Tahr), and Ubuntu 12.04 LTS (Precise Pangolin), as well as all of their official or unofficial derivatives running the same kernel builds.

Mad Max Now on GNU/Linux

  • Mad Max Open World Action-Adventure Video Game Released for Linux, SteamOS & Mac
    After teasing us earlier this month, today, October 20, 2016, Feral Interactive had the great pleasure of announcing the release of the Mad Max open world action-adventure video game for the SteamOS, Linux, and Mac platforms. Feral Interactive is well known for bringing AAA titles to the Linux and Mac gaming world, and after porting the Tomb Raider 2013 reboot last year to our beloved platforms, which continue to get more fans by the day, now the UK-based video games publisher delights us with the superb Mad Max title developed by Avalanche Studios and published by Warner Bros.
  • Mad Max Launches For Linux
    Feral Interactive's port of Mad Max to Linux (and macOS) is now officially out and can be found on Steam. Feral announced their Mad Max port at the beginning of October while today it's ready to ship. As mentioned in that original article, the Linux system requirements are fairly stiff with only listing NVIDIA hardware under Linux and the minimum being a GTX 660 while the recommendation is at least a GTX 970.
  • Mad Max Appears To Work Fine With RadeonSI Gallium3D
    This morning's release of the Mad Max game for Linux lists only NVIDIA graphics as supported, but it does turn out at least for newer AMD GPUs using the RadeonSI Gallium3D driver things should work -- well, assuming you are using the latest open-source driver code.
  • Mad Max released for Linux, port report and review available
    Mad Max is the latest Linux port from Feral Interactive, probably one of the titles I have been most excited about so hopefully it lives up to the promise. It has only been a few weeks since Feral Interactive released Dawn of War II, Chaos Rising and Retribution on Linux, and now we have a real whopper with Mad Max. Something Linux lacks is a reasonable amount of high quality open-world story-based games. We started getting a few with Borderlands 2 and Shadow of Mordor, but another top quality game like this is a must for us to keep the interest up.

Red Hat and Fedora

  • Red Hat – the open source conglomerate
    As successful companies grow, they accumulate products; new ones are developed and additional ones are acquired. Managing diverse portfolios is a challenge, not least when it comes to putting it all together on a single presentation slide to make it appear there is an overall coherent product strategy.
  • Ericsson Embraces Red Hat OpenStack Platform
    Ericsson and Red Hat today announced a broad alliance to work together on network functions virtualization (NFV) products. And the telco infrastructure provider will now support the Red Hat OpenStack Platform. Ericsson already has a longstanding distribution partnership with Red Hat that includes Red Hat Enterprise Linux and Red Hat JBoss Middleware. The existing distribution partnerships define not only commercial terms, but also joint support models, co-engineering and certification testing, and joint go-to-market collaboration.
  • Raleigh's Red Hat teams up with Ericsson
    Open-source software firm Red Hat (NYSE: RHT) has teamed up with Ericsson (Nasdaq: ERIC) on what the companies are calling a “broad alliance” aimed at transforming the information and communications technology market. Red Hat, headquartered at downtown Raleigh’s Red Hat Tower, announced that its new partnership with Ericsson would allow the duo to deliver fully open-source and production-ready cloud infrastructure, spanning OpenStack, software-defined networking and software-defined infrastructure.
  • FCAIC in the House
    The job is like many other roles called “Community Manager” or “Community Lead.” That means there is a focus on metrics and experiences. One role is to try ensure smooth forward movement of the project towards its goals. Another role is to serve as a source of information and motivation. Another role is as a liaison between the project and significant downstream and sponsoring organizations. In Fedora, this means I help the Fedora Project Leader. I try to be the yen to his yang, the zig to his zag, or the right hand to his right elbow. In all seriousness, it means that I work on a lot of the non-engineering focused areas of the Fedora Project. While Matthew has responsibility for the project as a whole I try to think about users and contributors and be mechanics of keeping the project running smoothly.
  • keepalived: Simple HA
    We have been using keepalived in Fedora Infrastructure for a while now. It’s a pretty easy to use and simple way to do some basic HA. Keepalived can keep track of which machine is “master” for a IP address and quickly fail over and back when moving that IP address around. You can also run scripts on state change. Keepalived uses VRRP and handles updating arp tables when IP addresses move around. It also supports weighting so you can prefer one or another server to “normally” have the master IP/scripts.
  • What does Factory 2.0 mean for Modularity?
    This blog now has a drop-down category called Modularity. But, many arteries of Modularity lead into a project called Factory 2.0. These two are, in fact, pretty much inseparable. In this post, we’ll talk about the 5 problems that need to be solved before Modularity can really live. The origins of Factory 2.0 go back a few years, when Matthew Miller started the conversation at Flock. The first suggested names were “Fedora Rings”, “Envs and Stacks”, and Alephs.
  • varnish-5.0, varnish-modules-0.9.2 and hitch-1.4.1, packages for Fedora and EPEL
    The Varnish Cache project recently released varnish-5.0, and Varnish Software released hitch-1.4.1. I have wrapped packages for Fedora and EPEL. varnish-5.0 has configuration changes, so the updated package has been pushed to rawhide, but will not replace the ones currently in EPEL nor in Fedora stable. Those who need varnish-5.0 for EPEL may use my COPR repos at They include the varnish-5.0 and matching varnish-modules packages, and are compatible with EPEL 5, 6, and 7.

Security News

  • Security advisories for Thursday
  • More information about Dirty COW (aka CVE-2016-5195)
    The security hole fixed in the stable kernels released today has been dubbed Dirty COW (CVE-2016-5195) by a site devoted to the kernel privilege escalation vulnerability. There is some indication that it is being exploited in the wild. Ars Technica has some additional information. The Red Hat bugzilla entry and advisory are worth looking at as well.
  • CVE-2016-5195
    My prior post showed my research from earlier in the year at the 2016 Linux Security Summit on kernel security flaw lifetimes. Now that CVE-2016-5195 is public, here are updated graphs and statistics. Due to their rarity, the Critical bug average has now jumped from 3.3 years to 5.2 years. There aren’t many, but, as I mentioned, they still exist, whether you know about them or not. CVE-2016-5195 was sitting on everyone’s machine when I gave my LSS talk, and there are still other flaws on all our Linux machines right now. (And, I should note, this problem is not unique to Linux.) Dealing with knowing that there are always going to be bugs present requires proactive kernel self-protection (to minimize the effects of possible flaws) and vendors dedicated to updating their devices regularly and quickly (to keep the exposure window minimized once a flaw is widely known).
  • “Most serious” Linux privilege-escalation bug ever is under active exploit (updated)
    While CVE-2016-5195, as the bug is cataloged, amounts to a mere privilege-escalation vulnerability rather than a more serious code-execution vulnerability, there are several reasons many researchers are taking it extremely seriously. For one thing, it's not hard to develop exploits that work reliably. For another, the flaw is located in a section of the Linux kernel that's a part of virtually every distribution of the open-source OS released for almost a decade. What's more, researchers have discovered attack code that indicates the vulnerability is being actively and maliciously exploited in the wild.
  • Linux users urged to protect against 'Dirty COW' security flaw
    Organisations and individuals have been urged to patch Linux servers immediately or risk falling victim to exploits for a Linux kernel security flaw dubbed ‘Dirty COW'. This follows a warning from open source software vendor Red Hat that the flaw is being exploited in the wild. Phil Oester, the Linux security researcher who uncovered the flaw, explained to V3 that the exploit is easy to execute and will almost certainly become more widely used. "The exploit in the wild is trivial to execute, never fails and has probably been around for years - the version I obtained was compiled with gcc 4.8," he said.
  • Hackers Hit U.S. Senate GOP Committee
    The national news media has been consumed of late with reports of Russian hackers breaking into networks of the Democratic National Committee. Lest the Republicans feel left out of all the excitement, a report this past week out of The Netherlands suggests Russian hackers have for the past six months been siphoning credit card data from visitors to the Web storefront of the National Republican Senatorial Committee (NRSC). [...] Dataflow markets itself as an “offshore” hosting provider with presences in Belize and The Seychelles. Dataflow has long been advertised on Russian-language cybercrime forums as an offshore haven that offers so-called “bulletproof hosting,” a phrase used to describe hosting firms that court all manner of sites that most legitimate hosting firms shun, including those that knowingly host spam and phishing sites as well as malicious software. De Groot published a list of the sites currently present at Dataflow. The list speaks for itself as a collection of badness, including quite a number of Russian-language sites selling synthetic drugs and stolen credit card data. According to De Groot, other sites that were retrofitted with the malware included e-commerce sites for the shoe maker Converse as well as the automaker Audi, although he says those sites and the NRSC’s have been scrubbed of the malicious software since his report was published. But De Groot said the hackers behind this scheme are continuing to find new sites to compromise. “Last Monday my scans found about 5,900 hacked sites,” he said. “When I did another scan two days later, I found about 340 of those had been fixed, but that another 170 were newly compromised.”
  • Thoughts on the BTB Paper
    The Branch Target Buffer (BTB) whitepaper presents some interesting information. It details potential side-channel attacks by utilizing timing attacks against the branch prediction hardware present in Intel Haswell processors. The article does not mention Intel processors later than Haswell, such as Broadwell or Skylake. Side-channel attacks are always interesting and fun. Indeed, the authors have stumbled into areas that need more research. Their research can be applicable in certain circumstances. As a side-note, KASLR in general is rather weak and can be considered a waste of time[1]. The discussion why is outside the scope of this article.
