Security update for OpenJDK7

December 7, 2017 / / 1 Comment

icedteaIcedTea release manager Andrew Hughes (aka GNU/Andrew) announced the announced a new release for IcedTea. The version 2.6.12 builds OpenJDK 7u161_b01. This release includes the October 2017 security fixes for Java 7. The announcement page contains a list of the security issues that have been fixed with this release. It is recommended that you upgrade your OpenJDK 7 to the latest version. If you have already moved to Java 8 then this article is obviously not relevant for you.

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.

OpenJDK8 security update November 2017

November 2, 2017 / / 1 Comment

icedteaOn the ‘distro packagers‘ mailing list for OpenJDK there was an announcement today that IcedTea 3.6.0 is ready, and allows building of the OpenJDK 8u151_b12 (Java 8 Update 151).The official October 2017 security fixes for Java 8 are applied, and the announcement contains a long list of CVE entries that are being addressed.

You can download openjdk and openjre packages for Slackware 13.37 and newer:

If you want to compile the OpenJDK package from source yourself you will need to install apache-ant first, but this package is not needed if you just want to run Java using the JRE or compile Java code using the JDK.

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.

Have fun! Eric

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.

Q4 2016 fixes for Java 8 (openjdk)

November 9, 2016 / / 1 Comment

icedteaThe icedtea project have released version 3.2.0 of their IcedTea build framework. This was done to mirror Oracle’s recent Critical Patch Update which brings OpenJDK to version 8u111_b14 or “Java 8 Update 111 Build 14”  (and the JRE too of course).

Here is the long-ish 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 (updates for Slackware 13.37 and 14.0 are still pending):

http://www.slackware.com/~alien/slackbuilds/openjdk/

http://bear.alienbase.nl/mirrors/people/alien/slackbuilds/openjdk/
(rsync URI: rsync://bear.alienbase.nl/mirrors/people/alien/slackbuilds/openjdk/)

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.

Have fun! Eric
