I am not sure if any of the previous version are affected or if only the current release is affected. The primary concern is Java applets run by your browser. The vulnerability allows a zero-day browser exploit that as yet is not patched by Oracle. The primary concerns I have heard of are installation of keyloggers and installation of ransomware. I would assume the malware will use the JVM to run and would be cross platform. AFAIK, Oracle has not yet announced when a patch will be available. It is highly recommended that Java be disabled in your browser(s) regardless of the version. Note JavaScript is not affected, it is entirely different than Java. Currently this warning does not cover non-browser applications that use the JVM. If you use Firefox and update your operating system regularly, Firefox should have already disabled the JVM add-on. Check Tools - Add-ons for it if you use Firefox. Also check the Help section for specific information about how to disable Java in your browser. --Dan -- For unsubscribe instructions e-mail to: users+h...@global.libreoffice.org Problems? http://www.libreoffice.org/get-help/mailing-lists/how-to-unsubscribe/ Posting guidelines + more: http://wiki.documentfoundation.org/Netiquette List archive: http://listarchives.libreoffice.org/global/users/ All messages sent to this list will be publicly archived and cannot be deleted

Re: [libreoffice-users] Embedded Java
Hi :) OpenJDK is also owned by Oracle. (it shocked me when i found that out too! lol) It tends to be a lot less likely to run into problems because the strong community involved seems to take the edge off it a lot but ultimately it is still owned by Oracle. Many such community run but owned projects have broken free of Oracle over the past couple of years but if OpenJdk did that then they would have problems maintaining their position of being a drop-in replacement for the proprietary version.

Re: [libreoffice-users] Embedded Java
Hi :) I think it's less of a problem on any unix-based platform even using Oracle's main versions. Mac had a problem with 2 old versions but generally the main problems are on Windows because it's much easier for a remote attacker to escalate their privileges. In Mac but even more so in GnuLinux it's quite normal to run things as a normal user without Superuser privileges. The whole Windows culture is for users to set their normal/only user as SuperUser otherwise stuff just doesn't work. Notice that Oracle's main version of java keeps getting upgraded. Typically at least 1/month. It's always about security and they always advise people to upgrade to their newest version because of security problems with their older one (last month's). Then the month later they say there was a problem with the one they said was safe last month. The 1st 4 or 5 versions in their newer branch weren't even released apparently because they got compromised even before they got released. OpenJdk doesn't seem to be so perpetually troubled. Personally i think that's due to the community taking notice of their bug-reports and being more careful about their coding. More eyes on the code surely helps 'obvious' troublesome areas.

Many such community run but owned projects have broken free of Oracle over the past couple of years but if OpenJdk did that then they would have problems maintaining their position of being a drop-in replacement for the proprietary version. Is it owned by Oracle? Or do they just contribute to it? Other companies, such as IBM and Apple also contribute. Also, from what I've been reading, this is a problem with using Java with browsers. Linux uses something called IcedTea to replace Oracle components that are not open source. Might the difference in their avoid the problem? Also, as for a drop in replacement, it only has to function as the original, that is same APIs etc. It does not mean the same source code. So, if the problem is with the way Oracle's version was implemented, that may mean other versions do not have the same problem. https://en.wikipedia.org/wiki/Openjdk -- For unsubscribe instructions e-mail to: users+h...@global.libreoffice.org Problems? http://www.libreoffice.org/get-help/mailing-lists/how-to-unsubscribe/ Posting guidelines + more: http://wiki.documentfoundation.org/Netiquette List archive: http://listarchives.libreoffice.org/global/users/ All messages sent to this list will be publicly archived and cannot be deleted

The warnings were specific to Oracle's implementation not any other version. I do not know if this a simplification by the writers/editors or if only Oracle's implementation is affected. Being cautious, I would assume if an implementation is not specifically cleared I assume it is also vulnerable. Apparently this vulnerability can lead to some very nasty malware exploiting the system. To be safe I would disable Java (not JavaScript) in all web browsers until patches are issued. From what I understand disabling Java will have a minimal impact for most users on the Web. -- Jay Lozier jsloz...@gmail.com -- For unsubscribe instructions e-mail to: users+h...@global.libreoffice.org Problems? http://www.libreoffice.org/get-help/mailing-lists/how-to-unsubscribe/ Posting guidelines + more: http://wiki.documentfoundation.org/Netiquette List archive: http://listarchives.libreoffice.org/global/users/ All messages sent to this list will be publicly archived and cannot be deleted
