April security updates for (open) Java 7 and 8

April 25, 2016 / / 12 Comments

icedteaUpdates are available both for Java 7 and java 8. These updates sync the OpenJDK releases to the April 2016 updates from Oracle’s Java.

Java 8

The recently released icedtea-3.0.1 builds OpenJDK 8u91_b14 aka Java 8 Update 91, with security fixes and CVE‘s related to Oracle’s April 2016 updates:

  • S8129952, CVE-2016-0686: Ensure thread consistency
  • S8132051, CVE-2016-0687: Better byte behavior
  • S8138593, CVE-2016-0695: Make DSA more fair
  • S8139008: Better state table management
  • S8143167, CVE-2016-3425: Better buffering of XML strings
  • S8143945, CVE-2016-3426: Better GCM validation
  • S8144430, CVE-2016-3427: Improve JMX connections
  • S8146494: Better ligature substitution
  • S8146498: Better device table adjustments

Java 8 contains its own JavaScript engine so there is no longer a dependency on a separate “rhino” package.

Java 7

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.

The icedtea-2.6.6 release builds OpenJDK 7u101_b00 aka Java 7 Update 101. There’s a list of security fixes attached to this release, almost identical to the Java 8 list:

  • S8129952, CVE-2016-0686: Ensure thread consistency
  • S8132051, CVE-2016-0687: Better byte behavior
  • S8138593, CVE-2016-0695: Make DSA more fair
  • S8139008: Better state table management
  • S8143167, CVE-2016-3425: Better buffering of XML strings
  • S8144430, CVE-2016-3427: Improve JMX connections
  • S8146494: Better ligature substitution
  • S8146498: Better device table adjustments

The Java 7 package (openjre7 as well as openjdk7) has one dependency: rhino provides JavaScript support for OpenJDK.

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.

Icedtea 3.0.0 brings Java 8 to Slackware

April 11, 2016 / / 8 Comments

icedteaFinally! IcedTea 3.0.0 has been released and it compiles OpenJDK 8u77.

Java 8 has been available for considerable time, but I have been waiting for icedtea to support it before creating packages. According to release maintainer Andrew Hughes the main cause for this delay was having to start from scratch due to the new build system and basically lack of time.

I want to use IcedTea as a “build harness” for OpenJDK because it makes openjdk interoperate with the free icedtea-web browser plugin and adds support for Java Virtual Machines for other architectures than just x86 and x86_64 (CACAO and JamVM in addition to Hotspot). Note that in this initial release of the icedtea-built OpenJDK, the alternative Java VMs are crash-prone – only Hotspot works properly. This means that currently OpenJDK for the ARM platform will be pretty slow because Hotspot is a zero-assembler VM.

So, Slackers can now upgrade their machines to OpenJDK 8 “Update 77 Build 03“. The Slackware packages are openjdk-8u77_b03 and openjre-8u77_b03. Get them from a mirror location below.

No security fixes and CVE‘s to report this time, since this is a first release. An icedtea-3.0.1 release with security fixes is expected in two weeks.

Java 7

For those of you who are not ready to migrate to Java 8, I have renamed the previous openjdk/openjre 7 packages to “openjdk7” and “openjre7”. Please use openjdk7 instead of openjdk (likewise, use openjre7 instead of openjre) and be aware that the 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. If you think that is an issue and you want – or need – to have both installed simultaneously, let me know in a comment to this article.

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.

The Java package (openjre as well as openjdk) has one dependency: rhino provides JavaScript support for OpenJDK. Rhino used to be an external dependency but since OpenJDK 8 it is internalized through the “nashorn” library.

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.

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

 

OpenJDK updated to 7u91_b01

October 25, 2015 / / 1 Comment

icedteaVersion 2.6.2 of IcedTea was released last week. I am working on a cool new idea (no guarantees that this will ever go public but if it works, you’ll know it) so the announcement kind of slipped my attention.

The IcedTea “build harness” for OpenJDK will compile OpenJDK 7 “Update 91 Build 01“. In Slackware terminology: here is the package openjdk-7u91_b01. The release synchronizes with Oracle’s october updates to OpenJDK. Read more about the release on the blog of release maintainer Andrew Hughes.

As with every Java release, this one comes with a list of  security fixes and CVE‘s which have been addressed and fixed:

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.

July ’15 OpenJDK security update: 7u85_b01

July 23, 2015 / / 1 Comment

icedtea A new release of IcedTea  is available. Version 2.6.1 came right after last week’s 2.6.0 which paved the way for OpenJDK 7 “Update 85 Build 01” (resulting in a Slackware package openjdk-7u85_b01). This latest version of icedtea encompasses the July 2015 security updates for Java7. The release announcement can be found on the blog of release maintainer Andrew Hughes.

The upcoming release of icedtea 3.0.0 will move us to OpenJDK 8, but for now it is Java 7 you’ll still be using if you install my packages. A bit of patience is required.

A list of  CVE’s is associated with the new release. Here are all security fixes mentioned in the post:

 

Note about usage:

Remember that I release packages for the JRE (runtime) 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. Get them here.

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 (which supports NPAPI plugins – this excludes Chrome & Chromium but you’ll be OK with all Mozilla [-compatible] browsers) 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.

If you want to test your browser plugin, check out the Java Tester page, or Oracle’s own verification page which of course urges you to upgrade to its own Java 8 instead:

OpenJDK-7u85_b01

If you want to compile this OpenJDK package yourself, you need to install apache-ant additionally. Note that the previous requirements of xalan & xerces packages have been dropped; ant will provide all required build functionality on its own now.

Have fun! Eric
