TuxMachines: Security Leftovers

Thursday 16th of March 2017 03:19:16 PM

  • Security updates for Thursday
  • Dormant Linux kernel vulnerability finally slayed

    A recently resolved vulnerability in the Linux kernel that had the potential to allow an attacker to gain privilege escalation or cause denial of service went undiscovered for seven years.

    Positive Technologies expert, Alexander Popov, found a race condition in the n_hdlc driver that leads to double-freeing of kernel memory. This Linux kernel flaw might be exploited for privilege escalation in the operating system. The (CVE-2017-2636) bug was evaluated as dangerous with a CVSS v3 score of 7.8, towards the higher end of the scale which runs from 1-10.

  • Another Years-Old Flaw Fixed in the Linux Kernel

    The Linux team has patched a "dangerous" vulnerability in the Linux kernel that allowed attackers to elevate their access rights and crash affected systems.

    The security issue, tracked as CVE-2017-2636, existed in the Linux kernel for the past seven years, after being introduced in the code in 2009.

These include the experimental MUFFIN user interface with a Microsoft Office-like Ribbon UI, as well as the first source release of LibreOffice Online.

During these past six weeks, LibreOffice 5.3.1 received two Release Candidate (RC) development versions, which fix about 100 bugs and regressions that have been either discovered by the LibreOffice developers/contributors or reported by users from the previous version.

Thursday 16th of March 2017 02:50:57 PM

With this week's LLVM 4.0 release making the LLD linker ready for production use on some platforms, namely ELF on x86_64 / AArch64, I decided to finally try it out on one of my test systems. I set LLD as the default linker on an Ubuntu 17.04 system and set off to run some benchmarks.

In a quest to remediate history, SUSE and partner LINBIT announced a solution that promises to change the economics of data replication. The two companies' collaborative effort is the headliner in the updated SUSE Linux Enterprise High Availability Extension, which now includes LINBIT's integrated geo-clustering technology. Read more

  • DRM display resource leasing (kernel side)
    So, you've got a fine head-mounted display and want to explore the delights of virtual reality. Right now, on Linux, that means getting the window system to cooperate because the window system is the DRM master and holds sole access to all display resources. So, you plug in your device, play with RandR to get it displaying bits from the window system and then carefully configure your VR application to use the whole monitor area and hope that the desktop will actually grant you the boon of page flipping so that you will get reasonable performance and maybe not even experience tearing. Results so far have been mixed, and depend on a lot of pieces working in ways that aren't exactly how they were designed to work.
  • GUADEC accommodation
    At this year’s GUADEC in Manchester we have rooms available for you right at the venue in lovely modern student townhouses. As I write this there are still some available to book along with your registration. In a couple of days we have to a final numbers to the University for how many rooms we want, so it would help us out if all the folk who want a room there could register and book one now if you haven’t already done so! We’ll have some available for later booking but we have to pay up front for them now so we can’t reserve too many.
