  Distro-agnostic app distribution and management tools like Snappy, Flatpak and AppImage are trend du jour right now. But I often wonder how many people out there are actually using these next-gen formats compared to existing ones, like PPAs and regular repositories. Snaps seem super popular, and there are AppImages for just about everything we mention on this site. But what of Flatpak?

Security: Windows 10 Bypass, Slackware OpenJDK Update and More

• [Older] GHOSTHOOK ATTACK BYPASSES WINDOWS 10 PATCHGUARD

  A bypass of PatchGuard kernel protection in Windows 10 has been developed that brings rootkits for the latest version of the OS within reach of attackers. Since the introduction of PatchGuard and DeviceGuard, very few 64-bit Windows rootkits have been observed; Windows 10’s security, in particular its mitigations against memory-based attacks, are well regarded. Researchers at CyberArk, however, found a way around PatchGuard through a relatively new feature in Intel processors called Processor Trace (Intel PT).

• [Slackware] OpenJDK 8 security round-up for July ’17

• ROI (Not Security) the Most Immediate IoT Challenge

  According to Defining IoT Business Models, a new report from Canonical, the software company behind the Ubuntu Linux distribution, device security and privacy (45 percent) falls behind quantifying the return of investment (ROI) of their IoT projects (53 percent) as an immediate challenge. Canonical drew its conclusions from a survey of 361 IoT professionals conducted by IoTNow on behalf of the company.

• Apply the STIG to even more operating systems with ansible-hardening

  Tons of improvements made their way into the ansible-hardening role in preparation for the OpenStack Pike release next month. The role has a new name, new documentation and extra tests. The role uses the Security Technical Implementation Guide (STIG) produced by the Defense Information Systems Agency (DISA) and applies the guidelines to Linux hosts using Ansible. Every control is configurable via simple Ansible variables and each control is thoroughly documented.

• SECURITY FOR THE SECURITY GODS! SANDBOXING FOR THE SANDBOXING THRONE

  Last year, probably as a distraction from doing anything else, or maybe because I was asked, I started reviewing bugs filed as a result of automated flaw discovery tools (from Coverity to UBSan via fuzzers) being run on gdk-pixbuf. Apart from the security implications of a good number of those problems, there was also the annoyance of having a busted image file bring down your file manager, your desktop, or even an app that opened a file chooser either because it was broken, or because the image loader for that format didn't check for the sanity of memory allocations.
