Java - new zero day vulnerability - new release Java 7u11

A new Java zero-day security vulnerability is already being actively exploited to compromise PCs. The best way to defend against the attacks is to disable any Java browser plugins on your systems.
The offending bug is present in fully patched and up-to-date installations of the Java platform, now overseen by database giant Oracle, according to Jaime Blasco, head of labs at security tools firm AlienVault.
Now the really interesting part for me is I use Firefox with the fully up to date version - and Firefox has disabled it by itself

Re: Java - new zero day vulnerability

There's a method built in to Firefox where Mozilla can add addons and plugins to a blacklist, so Firefox will automatically disable them... so that's not really a huge surprise Smiley
Do (m)any websites actually still use Java applets these days?

Re: Java - new zero day vulnerability

Now that is interested - I just ran the update check and it doesn't check plugins which are disabled
So once disabled it stays disabled for ever unless a new version is installed by a third party and then both versions seem to be there

Re: Java - new zero day vulnerability

I think you need to go through the total removal of Java procedure and start again.

Re: Java - new zero day vulnerability

I just enabled it and ran the check and it says it is up to date - now disabled again
I also did a reinstall 2 days ago and running it again it shows as being up to date

Did you do a full Java uninstall first? http://www.java.com/en/download/uninstall.jsp

Re: Java - new zero day vulnerability

No I didn't as I thought that wasn't necessary any more - now going to do it - but won't reinstall unless I really need it
Also removing JavaFX as I have no idea where that came from

Re: Java - new zero day vulnerability

Also I have been through my PC (Win7) and SWBO (XP) and updated or removed a few addons.
The most difficult needed a dll delete having found the source using about:plugins but the worst was a blocked uplay plugin which was really well hidden (it was in the ubisoft directory and wasn't listed in the about:addons list)

Re: Java - new zero day vulnerability

Thank you for the notice of this, Jim. Timely, as I was just about to create new backups before updating my Mozilla applications.

https://blog.avast.com/2012/08/30/how-do-i-disable-java-in-my-browser/ could be a useful guide for some (like me).

Re: Java - new zero day vulnerability

Very interesting, Jim.....
I use the following website quite a lot......
http://www.ship-tracking.co.uk/Main%20Menu/
click on SOLENT in the first box ( AIS MAPS )..... and the solent and I.o.W map appears, then the ships positions appear, then the map disappears.....
I reported it to the web owner, who advised me to disable the Jave cache.... and it cured the problem..... that was this morning..... 
been off out all day, and just tried it again.... and the map disappears... so it looks like Firefox has done the deed again, and disabled Java.....
Reported to the website owner, just now, with a linky to this thread....

Re: Java - new zero day vulnerability

Anyone else having problems with this site?
http://www.ship-tracking.co.uk/AIS%20Maps/solent.html
The background map disappears for me..... Website owner also uses FF, he said it reported Java shut down... but he still sees the map as a background to the ship positions as normal....

Re: Java - new zero day vulnerability

This is what I get with Firefox - I don't have Java installed

Re: Java - new zero day vulnerability

I could only see one tiny Java applet on that ship-tracking.co.uk page, I did not succeed in getting the Java applet to work, but because it's called SerifMarquee.class I'm guessing it's supposed to display some scrolling text beside "Please click this" in the top left corner. Not a vital part of the page.
The map works fine regardless of Java. I think the only problem was it once scrolled itself to the bottom of the page, where there is a big empty space, but I could not repeat that.
