June ’16 security fixes for Adobe Flash

June 17, 2016 / / 2 Comments

adobe_flash_8s600x600_2Earlier this week, there was already some talk about a zero-day exploit in Flash for which Adobe would be releasing a fix. And indeed they issued a Flash player  security update yesterday.

The updated plugin for the Chromium browser (chromium-pepperflash-plugin) has the version number 22.0.0.192 while the plugin for Mozilla browsers (flashplayer-plugin) moves up a tiny bit; to version 11.2.202.626.

Slackware packages for these Flash plugins are available for download & install in the following locations:

Note that the Chromium plugin comes as a 64bit package only. Google has ceased providing 32bit versions of their Chrome browser from which I take the plugin library. I do offer a 32bit Chromium package of course; it’s just lacking the proprietary 32bit plugins now (pepperflash & widevine).

If you are using the slackpkg+ extension for slackpkg, then you just run “slackpkg update && slackpkg upgrade flash”. Alternatively, you can subscribe to my repository RSS feed to stay informed of any updates.

Chromium 51 packages available

May 27, 2016 / / 25 Comments

chromium_iconGoogle updated the stable branch of the Chromium browser to a new major version number: “51”. An overview of the changes since the previous “50” release are found in Google’s git. Updated packages for Slackware 14.1 and -current are now available from my repository, for the download URLs see below.

The announcement on the Google Chrome Releases blog mentions a list of vulnerabilities that were addressed with this release. Here are the ones that got a CVE rating… it sure pays off to be a security researcher and find Google Chrome vulnerabilities:

  • [614767] CVE-2016-1695: Various fixes from internal audits, fuzzing and other initiatives.

 

As always, it is strongly advised to upgrade to this new version of Chromium. Get my chromium packages in one of the usual locations:

The widevine and pepperflash plugin packagess for chromium can be found in the same repository. The 64bit version of the Widevine plugin was updated with new libraries extracted from the official Google Chrome for Linux; the new Chrome does not contain a newer PepperFlash than what I already have in my repository.

Remember, even though I can still provide a 32bit Chromium browser, Google has ceased providing a 32bit version of their own Chrome browser – which means, no more updates to the 32bit PepperFlash and Widevine plugins.

Have fun! Eric

Chromium 49 packages address security issues; no more 32-bit binary plugins

March 7, 2016 / / 19 Comments

chromium_iconChromium 49 was announced on the Google Chrome Releases blog. I needed some time to compile package for my ‘ktown’ repository containing the KDE Plasma 5 environment. In fact it took more time than anticipated because I had upgraded my QEMU from 1.2.0 to 2.5.0 and that had unepected side effects: it severely affected the performance of the host server (running Slackware64 13.37 and a 2.6.37.6 kernel) and decreased the Virtual Machine speed to almost half. And when the VM froze while I was compiling chromium in it, I had enough. I reverted to QEMU 1.2.0 and all is well again.

Anyway, the new chromium 49.0.2623.75 release addresses a couple of security issues – some of these have a CVE number:

  • [$8000][560011] High CVE-2016-1630: Same-origin bypass in Blink. Credit to Mariusz Mlynski.
  • [$7500][569496] High CVE-2016-1631: Same-origin bypass in Pepper Plugin. Credit to Mariusz Mlynski.
  • [$5000][549986] High CVE-2016-1632: Bad cast in Extensions. Credit to anonymous.
  • [$3000][572537] High CVE-2016-1633: Use-after-free in Blink. Credit to cloudfuzzer.
  • [$3000][559292] High CVE-2016-1634: Use-after-free in Blink. Credit to cloudfuzzer.

  • [$2000][555544] Medium CVE-2016-1637: Information Leak in Skia. Credit to Keve Nagy.
  • [$1000][585282] Medium CVE-2016-1638: WebAPI Bypass. Credit to Rob Wu.
  • [$1000][572224] Medium CVE-2016-1639: Use-after-free in WebRTC. Credit to Khalil Zhani.
  • [$1000][550047] Medium CVE-2016-1640: Origin confusion in Extensions UI. Credit to Luan Herrera.
  • [$500][583718] Medium CVE-2016-1641: Use-after-free in Favicon. Credit to Atte Kettunen of OUSPG.
  • [591402] CVE-2016-1642: Various fixes from internal audits, fuzzing and other initiatives.

It is advised to upgrade to this version of Chromium.

Please note that Google has stopped providing 32-bit versions of Chrome for Linux. This means that I will no longer be able to supply 32-bit plugins for Pepper Flash and for Widevine CDM support. The 32-bit plugins currently in my repository are taken from the Chrome 48 RPM and they will probably just keep functioning for a while. However I have no idea when they break, and particularly the Pepper Flash plugin will age pretty fast, considering the fact that Adobe releases security updates for Flash almost every month. YMMV.

Get my chromium packages in one of the usual locations:

The widevine and pepperflash plugin packagess for chromium can be found in the same repository.

December ’15 security fixes for Adobe Flash

December 9, 2015 / / 2 Comments

adobe_flash_8s600x600_2Adobe’s Flash player  security update for December was announced yesterday, which adddress several vulnerabilities. I packaged the updates as usual and my repository is up-to-date.

The new plugin for the Chromium browser (chromium-pepperflash-plugin) has the version number 20.0.0.228. The plugin for Mozilla browsers (flashplayer-plugin) has version 11.2.202.554.

The PepperFlash plugin is extracted from the official Google Chrome 47.0.2526.80 RPMs.

My download locations for the Flash plugin packages are as always:

If you are using the slackpkg+ extension for slackpkg, then you just run “slackpkg update && slackpkg update flash”. Alternatively, you can subscribe to my repository RSS feed to stay informed of any updates.

Last week’s security updates

November 16, 2015 / / 2 Comments

adobe_flash_8s600x600_2Adobe released updated Flash player plugins last tuesday, but I was too busy with other things to write a blog post about it. However, I did release updated packages the day after! The updates are for chromium-pepperflash-plugin (to be used together with my chromium package) with new version 19.0.0.245, and flashplayer-plugin which now is at version 11.2.202.548.

The PepperFlash plugin was extracted from Google Chrome 46.0.2490.86 but I did not compile a new Chromium package from the sources bearing that version this time. You’ll have to wait for the next stable release.

.

icedteaVersion 2.6.3 of IcedTea was also released last week. This version of IcedTea will compile OpenJDK 7 “Update 91 Build 02“. The release adds one missed security fix from Oracle’s october updates to OpenJDK. I could not find the announcement on the blog of release maintainer Andrew Hughes but here is his post on the mailing list instead.

The CVE which has been addressed and fixed:

  • S8142882, CVE-2015-4871: rebinding of the receiver of a DirectMethodHandle may allow a protected method to be accessed.

Note about OpenJDK usage:

I release packages for the JRE (runtime environment) and the JDK (development kit) simultaneously, but you only need to install one of the two. The JRE is sufficient if you only want to run Java programs (including Java web plugins). Only in case where you’d want to develop Java programs and need a Java compiler, you are in need of the JDK package.

The Java package (openjre as well as openjdk) has one dependency: rhino provides JavaScript support for OpenJDK.

Optionally: If you want to use Java in a web browser then you’ll have to install my icedtea-web package too. While Oracle’s binary JDK tarball contains a browser plugin, that one is closed-source and therefore Icedtea offers an open source variant which does a decent job. Note that icedtea-web is a NPAPI plugin – this prevents use of Java in Chrome & Chromium because those browsers only support PPAPI plugins, but you’ll be OK with all Mozilla [-compatible] browsers of course.

My download locations for these updated packages are as always:

If you are using the slackpkg+ extension for slackpkg, then you just run “slackpkg update && slackpkg update flash”. Alternatively, you can subscribe to my repository RSS feed to stay informed of any updates.

Have fun! Eric
