Security Issues with Javascript, Java Applet interaction

First the main idea of the project. I have a system where I need to use an applet to process an image and display it on a web page.
I have written the applet that does the image processing and it saves the finished image on the users disc. It then uses the showDocument(url) method to pass the URL of the local file to a java script function on the html page.
This is where the problem occurs. Firefox won't display that image and complains about a security error because the remote page is linking to a local file. Interestingly enough IE6 on windows has no issue displaying the generated image.
I really have two questions.
1)Is there a quick/dirty fix that just simply gets around the security barrier Firefox has?
2)Is there some other, more elegant, way of getting an image from an applet to the webpage. It doesn't matter if it requires writing to disc or not.
Thanks! Any suggestions out there will help me.

Issue with running Java applets on Safari 6.1

I conducted a system capability check on the course site I access (Defense Acquisition University) and one of the results indicated that I do not have the capability to run applets (requirements to run all courses). I verified my setings and I do have Java ver. 7 update 45 installed. I verified Safari's security preferences and confirmed that the "Enable Java Script" is checked. I tried configuring the website settings for Java plug-in but cannot figure out how to add url on the configured websites box. Is there any way to enable running applets in Safari? Any help is appreciated. Thanks in advance.

Please post a link to the page you're having trouble with (unless it requires a password.)

Using latest version of fireFox to access Think Central, pages will not load and they say that this is a security issue with FireFox?

Teachers in our district are supposed to use www.thinkcentral.com with FireFox.
Some have no problem accessing the lesson plans.
Most when they login click on a lesson plan and an icon shows up that says loading but never does.
If you reboot the computer and login you can open a page once but not a second time and no other lessons will open.
Think Central support says this is a security issue with Firefox.
I have updated FireFox, all the Adobe, Reader, Flash, Air and Shockwave. As well as Java.
I have allowed the pop ups to the think Central web site.
Any help would be appreciated

Are there any notification icons on the left end of the address bar? If so, please click them to see whether they related to security issues (such as blocked content - shield icon: [[How does content that isn't secure affect my safety?]]) or a plugin requiring permission (Lego-like icon).
Does Think Central have any help pages about this issue? Without an account, it is difficult to explore the issue first-hand.

Security issues with Lion

Anyone know what the real deal is with OS X Lion security. I've heard lots of things about how the recent Blackhat conference in Las Vegas said that Apple's security was not as good as Windows 7's. Anyone know anything about this? Thanks in advance for any feedback or input.

I've downloaded Java for OS X Lion 2012-001 to fix the security issues with Java but when I open it to install it gives me an error message saying don't open it as it has a disk image issue (?) and may make my computer less secure or cause other issues? I don't understand why it would cause security risks when it is supposed to be a patch to fix them?! Is it safe to go ahead and open/install?
Could that be why Apple has released Java for OS X Lion 2012-002 here: http://support.apple.com/kb/DL1515 ?

Severe Security Issue with Sharing Permissions and Windows

I recently discovered a severe Security issue with the windows sharing an permission settings:
I have two users, an admin user and a parental controlled user. On my mac mini, i have a external harddrive connected. On the harddrive, i have three folders, Itunes, Iphoto (Package) and a Temp Folder. I want to share the Harddrive RW for the admin, but only R for the parental user. But the Temp folder should be accessible for RW for the parental as well.
1. I set the Drive checkbox "ignore ownership" off.
2. I set the permissions of the drive to admin RW, parental R and Everyone to "no access"
3. I apply to enclosed Items
4. I set the permission of the Temp folder to admin RW, parental RW and Everyone to "no access"
5. I apply to enclosed Items
6. I go to "File Sharing" in the Preferences and activate SMB sharing for both users
7. I delete all previous shares
8. I add the Disk and use the proposed permissions which are admin RW, parental R, Everyone "no access"
9. I add the Temp folder and use the proposed permissions which are admin RW, parental RW, Everyone "no access" - Funny, there is a new Group called "Temp" created which has custom access on both sharepoints
10. I connect to the mac over a Windows machine (NTLM auth set appropriatly). Now I try to create a folder on the root of the Disk share, I get a denied message.
BUT WHEN I GO INTO A SUBFOLDER (eg. ITUNES or IPHOTO), WHICH HAS ALSO JUST "R" PERMISSION FOR THE PARENTAL USER, I AM ABLE TO RW, DELETE AND DO EVERYTHING!!!
TO RECAPITULATE: THE SHARING PERMISSIONS ARE "R", AND THE FILE PERMISSIONS IN THE RESPECTIVE FOLDERS FOR THE RESPECTIVE USER ARE ALSO JUST "R". BUT THE USER CAN DO EVERYTHING IN THE SUBFOLDERS!!!

Your question is not quite clear, and no Mac can iOS, but anything and everything made by or for Microsoft carries a security risk.

Security issues with connecting pdf to database

I have a pdf form that is being called from a webform as part
of a web application. The PDF has two dropdown lists that I was
populating from a SQL Server Database. I had created a special user
that had select access only to the tables for the dropdowns.
My question is are there any known security issues with
regard to allowing a pdf to connect to a database this way. The PDF
is being called from a secure connection but I don't know if
opening this database connection to populate these dropdowns
exposes a security hole of any sort. If it does, do you have a
solution to make this secure? I am asking because another developer
on the project brought up the issue of this design creating a
security risk and I haven't been able to find anything online
discussing it either way.
Thanks!

Hello Maureen,
Thanks for posting, but I'm not sure I see if your question

Security Issues with 8.1 Pro

I have had several security issues with Windows 8.1 Pro.
I am curious if the following apps should be loaded by default:
CheckPoint.VPN
JuniperNetworks.JunosPulseVpn
SonicWALL.MobileConnect
F.vpn.client
These programs are installed on a fresh install of Windows 8.1 Pro but I do not think they should be. They are present prior to the install of any 3rd party programs or apps.
Thanks

I found them in my firewall list on my Windows 8.1 Pro installation and posted a question on a forum as well, though I don't think it was here. I don't believe anyone ever answered.
It looks as though these are parts of the bundled virtual private networking clients.
Note, for example, the "distributed by Microsoft as part of Windows 8.1" wording on this page:

Privacy/Security Issue with Adobe Flash 10

Not sure if anyone has noticed this or not, but there is a
bizarre (if minor) privacy/security issue with Adobe Flash Player
10. I came across it while attempting to upload a file to Flickr.
Previous versions of AFP do not exhibit this problem.
Specifics: using Firefox 3.x, Vista.
The problem: When Flickr calls the "open file" dialogue in
Flash 10 (in order to upload files) via the "Upload Photos and
Videos" link, at the bottom of the dialogue, to the right of the
"File Name" box, sits a common UI element that brings up a dropdown
menu of what appear to be (or at least are supposed to be) recently
viewed or downloaded or accessed files. Actually I'm not sure how
Flash 10 compiles or accesses this list of files, but at any rate,
a list of files come up.
The problem is that, as far as I can tell, the list of files
that come up reference a long list of files, some that are very old
and that no longer exist, and that there is no way that I can find
to clear the list. This is a minor security/privacy issue, as
generally there should be a way to prevent a dialogue from
displaying a long list of past-accessed files by clearing a cache
somewhere or other -- imagine if it was impossible to clear the
history of a web browser, for example -- this would be considered a
pretty significant privacy issue. I have tried everything from
flushing the browser cache to uninstalling and reinstalling the
browser to uninstalling and reinstalling Adobe Flash to using the
Flash Settings Manager to clear out the Flash saved sites to
turning off Vista indexing to clearing out Vista's Recent Items
list. None of these actions did anything to clear out this list of
files. I can find no references to these files anywhere when I use
Vista Search (with unindexed and system files searched as well),
and I can find no reference to the files anywhere in the registry
(I checked just in case Flash 10 was storing this index in some
really bizarre place.) I've linked to a screenshot below of what
I'm talking about -- most of the files listed below were deleted a
long, long time ago, and so I have no idea why this dialogue refers
to them.
Screenshot
Is there a simple work-around for this that I'm unaware of?
Even if there is, there needs to be some more obvious way to clear
out this list. Where is this information being stored, and what
criteria does this list use to "put a file on the list"?

Thanks for putting me on the right scent. That's what I'd
originally thought, too -- it's just that the file-> open dialog
was giving an entirely different list of files with other
applications, so I assumed that it must be Flash that was the
culprit. Turns out the reason it was different with Flickr was
because it was restricting the file results via a long string of
video and picture filetypes that are compatible with the Flickr
service.
It turns out the information I'm looking for is buried deep
within the registry. The only way to clear out this list of files
is to delete the following key (or specific subkeys):
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\ComDlg32\OpenSavePidl MRU
Seems more than a little stupid to store such information in
the registry if security is your concern. Vista beguiles me
sometimes.

Security issue with unlocking my iPhone 4?

I'm not sure if anyone here will be able to help me but I am trying to get my iPhone unlocked with AT&T. I bought my iPhone on contract through AT&T in December 2010. My account is in good standing. I paid my ETF, it's technically eligible to be unlocked. I called AT&T on April 9th for an unlock and it's now April 19th and still no wordd from them. I've called several times and they won't tell me what's going on other than that "there is a security issue with unlocking my iPhone and the issue is with Apple, but they are working on it." From my understanding, all AT&T needs is the unlock code to enter into the system and unlock it from there. I don't know what security issues could possibly exist that would create a problem. The only thing I can think of is that when I orginally bought my iPhone it turned out to be a lemon and had to get it replaced the day after I bought it. I did this through an Apple store since it was around Christmas. The IMEI number on my phone doesn't match the one AT&T has on file, but that shouldn't matter? I gave them the right IMEI number that is on my current phone. Does anyone know what "security issues" can exist when it comes to unlocking an iPhone 4?

Don't stress over the words used by the customer service people at AT&T. Half of them don't know what they're talking about more than half the time. You are probably correct in that it has something to do with their database being inaccurate.
Give it a few days, then contact them again and ask for it to be escalated.
Ignor rNair. The idea that Apple made it mandatory for AT&T to do anything is complete and total bunk. (S)He has no idea what (s)he's talking about

Security issues with cached applets

Question: Can anyone tell me where there is a summary or discussion of security issues relating to applets cached by the Java Plug-in?
I'd like to use the Plug-in to cache applets on client boxes, but I'm wondering if that opens a security hole for hostile/attack applets. Most of the write-ups on applet security I've seen only deal with security on the client side. Does Sun or anyone else address "cached-applet security" as it relates to the server from which it was downloaded?

The cached applets are treated as same as those downloaded from the net - permissions will be granted based on the original codebase - nothing more, nothing less.

Security issues with Applets

I have a web server that has access to a database server as i am able to create web pages with ASP and connect to the database fine using a DSN, i have created a web page that contains an applet, the applet attempts to connect to the database but i get a security error, how do i overcome this security issue, the sucurity error looks like this:
Exception: java.security.AccessControlException: accessdenied(java.lang.RuntimePermission accessClassInPackage.sun.jdbc.odbc)
Can anyone help??

There is a java.policy file in
C:\Program Files\JavaSoft\JRE\1.3.1\lib\security\java.policy
And a tool you can use in
C:\Program Files\JavaSoft\JRE\1.3.1\bin\policytool.exe
You might have to tell the policytool.exe where to open the java.policy file.
You can also just modify it in a text editor and save it as plain text when you are done.
I don't know which permission you should look for, but you can try with
grant {
permission java.security.AllPermission;
and remove or comment out the other lines. Make a backup of the policy file before you try it. Restart the browser.
Note that you have to do this on all client machines that wants to run your applet.
