OpenJDK7 and Flash Player security updates (Aug ’17)

August 10, 2017 / / 2 Comments

icedteaOn the blog of IcedTea release manager Andrew Hughes (aka GNU/Andrew) you can find the announcement for IcedTea 2.6.11 which builds OpenJDK 7u151_b01. This release includes the official July 2017 security fixes for Java 7. Note that the security updates for Java 8 were already pushed to my repository some time ago.

Here is where you can download the Slackware packages for openjdk7 and openjre7:

The “rhino” package (implementation of the JavaScript engine used by OpenJDK) is an external dependency for OpenJDK 7, you can find a package in my repository. If you want to compile OpenJDK7 yourself you will need apache-ant as well.

Note about usage:

My Java 7 and Java 8 packages (e.g. openjdk7 and openjdk… or openjre7 and openjre) can not co-exist on your computer because they use the same installation directory. You must install either Java 7 or Java 8.

Remember that 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.

adobe_flash_8s600x600_2There was a recent security update for the Flash Player plugin as well. The new version is 26.0.0.151 for both the PPAPI (Google Chrome and friends) and the NPAPI (Mozilla Firefox and friends) based plugins.

You can find Slackware packages for the Flash plugins in the following repositories (and probably many more mirrors):

OpenJDK 8 security round-up for July ’17

July 21, 2017 / / 6 Comments

icedteaSooner than I anticipated, there is an update for OpenJDK 8. Andrew Hughes (aka GNU/Andrew) announced the release of IcedTea 3.5.0. The new icedtea framework compiles OpenJDK 8 Update 141 Build 15 (8u141_b15). This release includes the official July 2017 security fixes.

No external dependency is required for OpenJDK 8 . But if you use Java in your web browser (a dying art) you’ll need the icedtea-web browser plugin. Coincidentally, a new release for that became available a few days ago, therefore I also built packages for the plugin.

The packages that I just uploaded are for Slackware 13.37 and newer. Here is where you can download them:

Note about usage:

My Java 7 and Java 8 packages (e.g. openjdk7 and openjdk… or openjre7 and openjre) can not co-exist on your computer because they use the same installation directory. You must install either Java 7 or Java 8.

Remember that 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.

Plugin support in Web Browsers:

If you want to use Java in a web browser then you’ll have to install my icedtea-web package too. Oracle’s JDK contains a browser plugin, but that one is closed-source. Therefore Icedtea offers an open source variant which does a decent job.

Note that icedtea-web is a NPAPI plugin – this prevents the use of Java in Chrome & Chromium because those browsers only support PPAPI plugins. Formally, Mozilla have also ceased to support the NPAPI plugins. For instance Firefox 52 and newer does not support NPAPI plugins, although Firefox ESR 52 still supports them. If you can’t do without, then you can use Java plugins with the Pale Moon browser, which is based on an older Firefox codebase and maintained independently. Get my package here (it has ffmpeg as an external dependency): http://www.slackware.com/~alien/slackbuilds/palemoon/

OpenJDK security updates Jun’17

May 19, 2017 / / 3 Comments

icedteaFor all lovers and haters of Java: new releases are available for OpenJDK versions 7 as well as 8. On the blog of release manager Andrew Hughes (aka GNU/Andrew) you can find announcements for IcedTea 2.6.10 (which builds OpenJDK 7) and 3.4.0 (which builds OpenJDK 8). The new OpenJDK 7 and 8 releases include the official April 2017 security fixes.

You may think what you want about Java, but it is an important piece of software tech and ubiquitous, so I will keep releasing Slackware packages for as long as I can. My package support goes back to Slackware 13.37 which is the oldest release I personally recommend – if you are using an even older release, it’s probably because your hardware is very old or weak… in that case, you do not want to use something like Java anyway.

Here is where you can download the Slackware packages:

The “rhino” package (implementation of the JavaScript engine used by OpenJDK) is an external dependency for OpenJDK 7, you can find a package in my repository. It is not needed for OpenJDK 8 because that contains its own internal implementation of a JavaScript engine, called Nashorn.

Note about usage:

My Java 7 and Java 8 packages (e.g. openjdk7 and openjdk… or openjre7 and openjre) can not co-exist on your computer because they use the same installation directory. You must install either Java 7 or Java 8.

Remember that 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.

Plugin support in Web Browsers:

If you want to use Java in a web browser then you’ll have to install my icedtea-web package too. Oracle’s JDK contains a browser plugin, but that one is closed-source. Therefore Icedtea offers an open source variant which does a decent job.

Note that icedtea-web is a NPAPI plugin – this prevents the use of Java in Chrome & Chromium because those browsers only support PPAPI plugins. Formally, Mozilla have also ceased to support the NPAPI plugins. For instance Firefox 52 and newer does not support NPAPI plugins, although Firefox ESR 52 still supports them.

OpenJDK 7 security update Jan ’17

February 15, 2017 / / 1 Comment

icedteaAndrew Hughes (aka GNU/Andrew) has created a new release for IcedTea 2.6.x (which is the series targeting Java7) to allow the creation of an OpenJDK 7 package with the Java security fixes for January 2017 included.

I do realize that Java8 is the more popular version currently but as long as there are security updates for OpenJDK 7, I will try to put those into Slackware packages. So today, here’s OpenJDK 7u131_b00 – or “Java 7 Update 131 Build 00” for you. In fact two packages as always: the JRE and the JDK (which includes the JRE).

As is customary, Andrew provides release notes on his blog that list the vulnerabilities (CVE’s) which are being plugged with the new release. I used to paste those into my own blog articles but I rather give Andrew the credits, so please visit his latest post dubbed “[SECURITY] IcedTea 2.6.9 for OpenJDK 7 Released!“.

If you are still in need of Java 7 and have my older package installed, please upgrade your OpenJDK 7 to this new release. Here is where you can download the Slackware packages:

The “rhino” package (implementation of the JavaScript engine used by OpenJDK) is an external dependency for OpenJDK 7, you can find a package in my repository.

Note about usage:

My Java 7 and Java 8 packages (e.g. openjdk7 and openjdk… or openjre7 and openjre) can not co-exist on your computer because they use the same installation directory. You must install either Java 7 or Java 8.

Remember that 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.

Optionally: If you want to use Java in a web browser then you’ll have to install my icedtea-web package too. Oracle’s JDK contains a browser plugin, but that one is closed-source. Therefore Icedtea offers an open source variant which does a decent job.

Plugin support in Web Browsers:

Note that icedtea-web is a NPAPI plugin – this prevents the 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. For how long, I do not know. Mozilla have announced they will deprecate NPAPI in their browsers back in 2015.
And even though the plugins are still supported (but require manual activation now) there’s a very recent post on the blog of Firefox software engineer Mike Kaply where he mentions that Firefox 52 will be the first release that will no longer support NPAPI plugins at all (except for Flash but only for a few more releases to come). Remember, we are currently at Firefox version 51. Mike Kaply also mentions that the ESR releases of Firefox (i.e. the Extended Support Releases) will continue to support the NPAPI plugins!
So: Firefox 52: no more plugins. And Firefox ESR 52: plugins still supported.

Have fun! Eric

Openjdk (Java8) updated with January fixes

January 29, 2017 / / 3 Comments

icedteaThe icedtea project have released version 3.3.0 of their IcedTea build framework. This release updates the OpenJDK 8 support with the October 2016 bug fixes from OpenJDK 8 u112 and the January 2017 security fixes from OpenJDK 8 u121. Another point of notice is that improved font rendering is being worked on. The ‘infinality patches’ to freetype will be used for this. While I did not enable it in my package, IcedTea no longer requires a patched freetype. Infinality support should be enabled by default from IcedTea 3.4.0 onwards.

Compiling OpenJDK using IcedTea has resulted in the openjdk-8u121_b13 package for Slackware (Java 8 Update 121 Build 13). Next to the JDK there’s also the JRE package of course.

Here is list of security fixes and CVE‘s as taken from the announcement on Andrew Hughes’s blog:

Download locations for the JDK and JRE packages:

If your applications are not yet ready for Java 8, I still maintain the Java 7 packages under new names:”openjdk7″ and “openjre7”. Note that my Java 7 and Java 8 packages (e.g. openjdk7 and openjdk) can not co-exist on your computer because they use the same installation directory.

There is no more need for a separate “rhino” package (implementation of the JavaScript engine used by OpenJDK) because in OpenJDK 8, this functionality is provided natively using the internal “nashorn” library.

Note about usage:

Remember that 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.

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 JDK 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.
