Update for Chromium 45

September 27, 2015 / / 1 Comment

chromium_iconGoogle updated their Chrome/Chromium with mention of some security fixes. I had to finish compiling LibreOffice first, and also it takes a while for the official chromium source tarball to appear on Google’s servers. But the weekend started uneventful so it was easy to build you some new packages for the chromium browser inbetween baking some tasty sourdough bread. Accompanied by packages for the widevine plugin (a closed-source non-free plugin which allows you to watch Netflix in particular).

The security fixes in chromium 45.0.2454.101 have CVE numbers:

  • [$TBD][530301] High CVE-2015-1303: Cross-origin bypass in DOM. Credit to Mariusz Mlynski.
  • [$TBD][531891] High CVE-2015-1304: Cross-origin bypass in V8. Credit to Mariusz Mlynski.

Chromium 44 available (Netflix still works)

July 24, 2015 / / 22 Comments

chromium_iconI have made new packages for the chromium browser and its widevine plugin. Chromium version 44 was released a bit earlier this week, and it took me a while to compile, because the new OpenJDK 7u85 and LibreOffice 5.0.0.rc3 packages were ahead of it in the build queue. Guess what… now that I am writing this blog article after uploading the packages for chromium-44.0.2403.89, I notice that there was a second release of Chromium 44 Stable… today. Which makes me wonder if there was a regression in the earlier source release.

That updated version 44.0.2403.107 may have to wait, because I will be unable to do a lot of Slackware related stuff until august; real life is catching up with me. If there are real useability issues with 44.0.2403.89, let me know and I will see if I can shift priorities or make the older 43.x packages available again. My initial (not exhaustive) testing showed no weirdness at least.

Regardless, it took a few iterations before I got the Widevine CDM adapter to compile properly. I had to look at my chromium-dev package’s history to remember what had changed in version 44. Once I applied that knowledge to the stable sources, it all began to come together. Netflix still works 🙂 … well, after you’ve installed/upgraded my chromium-widevine-plugin package of course. which contains the proprietary Content Decryption Module.

The new chromium source I compiled into a package, comes with several security fixes, and here are the CVE’s:

Stable channel for Chromium hits 43

May 20, 2015 / / 16 Comments

chromium_iconBuilding on my experiences with chromium-dev (the development channel of the Chromium browser which is currently at version 44), I have made similar changes to my latest package for the chromium browser and its widevine and pepperflash plugins.

This means that I have said goodbye to the single configuration file (/etc/default/chromium) and switched to a configuration directory, which is “/etc/chromium/” for the chromium package. Each package (Chromium as well as any plugin or extension) can add its own configuration file to that directory. The new packages for chromium, chromium-pepperflash-plugin and chromium-widevine-plugin are now using this new setup.

I made one other change: I have applied a patch taken from an Ubuntu PPA. That patch is based on a blog post which explains how to enable VAAPI (aka hardware video decoding) on Linux. The chromium sources disable this functionality by default if you are not compiling for ChromeOS. Tell me your experiences with playback of H.264 video!

The new chromium packages have the version number 43.0.2357.65. The first release of the “43” series brings a total of 37 published security fixes, and here are the CVE’s:

  • [$16337][474029] High CVE-2015-1252: Sandbox escape in Chrome. Credit to anonymous.
  • [$7500][464552] High CVE-2015-1253: Cross-origin bypass in DOM. Credit to anonymous.
  • [$3000][444927] High CVE-2015-1254: Cross-origin bypass in Editing. Credit to Armin Razmdjou.
  • [$3000][473253] High CVE-2015-1255: Use-after-free in WebAudio. Credit to Khalil Zhani.
  • [$2000][478549] High CVE-2015-1256: Use-after-free in SVG. Credit to Atte Kettunen of OUSPG.

New chromium-dev package and plugins

May 15, 2015 / / 2 Comments

chromium_iconI have been working on some changes for the chromium package, and what’s better than to first test those changes on a Chromium Development release?

I have not really been happy with the choice I made to have a single configuration file (/etc/default/chromium) which would then have to be re-written by any plugins that you would install. For instance, the PepperFlash plugin modifies that file so that Chromium learns of the pathname and version of that plugin when it starts. Unfortunately, some people would accidentally wipe those modifications with every update to the Chromium main package (the “/etc/default/chromium.new” file would overwrite the “/etc/default/chromium” file if you were not paying attention).

So what I did was change the single configuration file into a configuration directory, which is “/etc/chromium-dev/” for the Chromium Dev package. Each package (Chromium as well as any plugin or extension) can add its own configuration file to that directory. As an example of how that works, I have created packages for chromium-dev, chromium-dev-pepperflash-plugin and chromium-dev-widevine-plugin that use this new setup. Those are Slackware packages  for -current only by the way – when a new version of Chromium Stable is released  I will also add this new configuration setup and then the packages will be released for Slackware 14.1 as well.

What else is there to say about my chromium-dev packages? Chromium-dev is the development release of the browser (there’s also a “beta” channel but I don’t care about that too much). Testing the development release from time to time is preparing me well in advance for major (or subtle) changes in the compilation process and functionality, so that when the stable channel jumps to a higher major release it won’t take me long to come up with a set of packages.

The new chromium-dev packages have the version number 44.0.2398.0. So what changed with this new major release 44 compared to the previous 43 (or even the stable 42)? One important change is that it is no longer necessary to extract the Widevine CDM library from an official Google Chrome RPM in order to compile the Open Source Widevine adapter library which is the piece of code that interfaces between the browser and the closed-source Content Decryption Module. Therefore even the Open Source purists should be at peace now with the new process. If you do want to use Widevine CDM, for instance when you want to stream Netflix in your Chromium browser, you simply install my widevine-plugin package (the version it reports will be 1.4.8.823). The browser itself will not be tainted.

The PepperFlash plugin package which I added as well (first time for my Chromium Dev releases) has a change as well, compared to the package for Chromium Stable. The PepperFlash directory is installed to “/usr/lib64/chromium-dev/” instead of “/usr/lib64/” (it’s “lib” for 32bit Slackware of course) so that the pepperflash-plugin package’s files will not clash with the pepperflash-plugin for Chromium Stable. The plugin for Chromium Dev reports itself as version 18.0.0.114 by the way. This version is not even listed yet on Adobe’s Flash test page. I assume that this too, is a development version.

Chromium: the answer to life, the universe and everything

April 16, 2015 / / 10 Comments

Chromium and Widevine:

chromium_iconGeeks and Sci-Fi fans, as well as otherwise properly educated people, will recognize the blog title for what it is.

Chrome 42 is released. Big jump: a major version change. Mostly changes under the hood again it seems. The Chrome binaries for this version contain a new version of the PepperFlash plugin, which I have extracted for use with the chromium browser – see my earlier blog. The packages for Slackware 14.1 and -current are available for download so that you can enjoy the latest Chromium browser (and its optional Widevine plugin) in your trustworthy Slackware environment.

In the  Chrome Releases blog you can read the announcement for Chrome/Chromium 42 to the Stable Channel (full version is 42.0.2311.90).

The new packages for my chromium and chromium-widevine-plugin packages both have version 42.0.2311.90 – indicating that they should be used together. The Widevine plugin reports itself as version “1.4.7.796” in chrome://plugins – same version as in my chromium-dev 43 package.

You don’t have to install the Widevine plugin. Chromium without Widevine plugin is a pure and open source browser, even the Widevine “adapter module” inside the Chromium package is open source. The Widevine library itself is a closed-source Content Decryption Module (CDM) which therefore is not part of the Chromium package but separately packaged (after extracting it from Google’s binary download of the Chrome browser with the same version number). You would typically want to install the plugin if you have a Netflix subscription and want to watch your movies in a Chromium browser.

Have fun! Next on the blog: new packages for VLC, the VideoLAN media player!
