Review: Kdenlive, the Linux video editor I want to use

Filed under

Reviews

There once was a time when video editing on Linux was an elusive beast.

Well, that's not exactly true. Professional-level video editing on Linux has been solid and mature for many years now, with the likes of Lightworks, Cinelerra and Blender. But the "hobbyist" video editor market just wasn't very well-served. There were video editors out there… but they were often buggy and lacking in critical features.

Why screen lockers on X11 cannot be secure

Filed under
KDE
Security

Today we released Plasma 5.2 and this new release comes with two fixes for security vulnerabilities in our screen locker implementation. As I found, exploited, reported and fixed these vulnerabilities I decided to put them a little bit into context.

The first vulnerability concerns our QtQuick user interface for the lock screen. Through the Look and Feel package it was possible to send the login information to a remote location. That’s pretty bad but luckily also only a theoretical problem: we have not yet implemented a way to install new Look and Feel packages from the Internet. So we found the issue before any harm was done.

Plasma 5.2 – The Quintissential Breakdown

Filed under
KDE

KDE is one of the oldest open-source desktop projects which can be found today, and over the years it has established a rich history of highs and lows. During some points it has been the undisputed ruler of the desktop world, while other times it had fallen behind or faced hard trials.

A memory everything but forgotten, just over 6 years ago KDE tore itself apart in spectacular fashion to assemble itself anew. Brave users who wandered through the rubble and wreckage saw developers rebuild the KDE before their eyes, witnessing the birth of ‘Plasma Desktop’ and it’s sister project ‘KDE Development Platform’. It was universally understood that this twisted gnarled creature of a computing experience was both hideous yet full of potential, and over 5 years of refining Plasma it had struggled, crawled, hobbled, walked, run, and eventually mature into a fine desktop.

KWin on speed

Filed under
KDE

With the 5.2 release basically done, I decided to do some performance investigation and optimizations on KWin last week. From time to time I’m running KWin through valgrind’s callgrind tool to see whether we have some expensive code paths. So far I hadn’t done that for the 5.x series. Now after the switch to kdecoration2 I was really interested in the results as in the past rendering the decoration used to be a bottle neck during our compositing rendering loop.

Fedora 22 Will Aim To Use Plasma 5 For Its KDE Desktop Experience

Filed under
KDE
Red Hat

For KDE users on Fedora, the Fedora 22 release is seeking to focus on the still-maturing Plasma 5 shell that's powered by KDE Frameworks 5 and Qt5.

An in-progress change proposal for Fedora 22 is to use Plasma 5 (and KF5/Qt5) with the latest KDE components to be fully-packaged in time for F22, an upgrade path be provided from KDE 4, and to retire any KDE 4 packages in Fedora that aren't compatible with the "KDE 5" work.

Security Leftovers

  • Security updates for Wednesday
  • Microsoft says its best not to fiddle with its Windows 10 group policies (that don't work)

    On Monday, we revealed that a security researcher had used a packet sniffer to show that many settings designed to prevent access to the internet were being ignored with connections to a range of third party servers including advertising hubs.

  • What's got a vast attack surface and runs on Linux? Windows Defender, of course
    Google Project Zero's Windows bug-hunter and fuzz-boffin Tavis Ormandy has given the world an insight into how he works so fast: he works on Linux, and with the release of a personal project on GitHub, others can too. Ormandy's project is to port Windows DLLs to Linux for his vuln tests (“So that's how he works so fast!” Penguinistas around the world are saying). Typically self-effacing, Ormandy made this simple announcement on Twitter (to a reception mixing admiration, humour, and horror):
  • Hacked in Translation – from Subtitles to Complete Takeover
    Check Point researchers revealed a new attack vector which threatens millions of users worldwide – attack by subtitles. By crafting malicious subtitle files, which are then downloaded by a victim’s media player, attackers can take complete control over any type of device via vulnerabilities found in many popular streaming platforms, including VLC, Kodi (XBMC), Popcorn-Time and strem.io. We estimate there are approximately 200 million video players and streamers that currently run the vulnerable software, making this one of the most widespread, easily accessed and zero-resistance vulnerability reported in recent years.
  • A Samba remote code execution vulnerability
    Distributors are already shipping the fix; there's also a workaround in the advisory for those who cannot update immediately.
