Is this bug of password security in Acrobat 9?

If you set password to "abcde" you can release it by input just "mz".
Or when longer password like "ABC-123456." then just input "x" to unsecure it.
I test on Acrobat 9.3.4.
If so, it is easy to unsecure all of secured pdf.

NEW !? ONLY !?
So user should avoid using older version of security format !?
I wonder if I test on the next version of acrobat, will it occur again or not when I set to old security format?

Hi shay_df,
Yes, the file is Reader enabled, and yes you have to create an unsigned copy of the file before you can remove the Password Security.
Open 1244.pdf
Type in the Document Open password (111111) and then click the OK button
Select the File > Save a Copy menu item
Click the Save a Copy button on the conformation dialog
Enter 1244_noUR.pdf as the File Name on the Save a Copy dialog, and then click the Save button
Type in the Document Open password (111111) and then click the OK button
Select the File > Open menu item
Navigate to, and then select the local copy of 1244_noUR.pdf, and then click the Open button
Type in the Document Open password (111111) and then click the OK button

Acrobat shuts down with an error every time I access Password security settings

Hi
I wonder if anyone can help me.
I have just bought Acrobat 8.1.2 professional, which I am using on a Windows XP machine.
When I enter the Password Security-Settings dialogue, about 2 seconds later, I get an error message saying that "Acrobat has encountered a problem and needs to close". When I click on "Send" or "Don't send", it then closes.
So I can't password protect my documents.
I experience this with a number of documents (including very, very simple ones), including pdfs I did not create.
I have run "repair" and also completely uninstalled and then reinstalled Acrobat,without success.
Has enyone else experienced this and found a solution?
Many thanks
Helena

I have now found a workaround for this! If you set the security settings you want as a security policy, and then apply that policy to your document (rather than trying to set the settings for the indoividual document), it all works fine without crashing.
It will mean that if you create lots of documents, all of which have slightly different security settings, you'll have a long list of policies, but I tend to use only about 2 security set ups, so it's fine for me. Hope it works for you too, L Haen.

This bug has been around for over a year: SecurityError: Error #2123: Security sandbox violation

Hi,
The bug of 'SecurityError: Error #2123: Security sandbox violation: BitmapData.draw: file:///xxx/xxx.swf cannot access rtmfp://fms4.acrobat.com/cocomo/na2-sdk-xxx/xxx. No policy files granted access.' was first reported in lccs forum over a year ago:
http://forums.adobe.com/message/2803074
But the bug is still around. The bug can be generated by calling BitmapData.draw() on a flash.media.Video object which is attached to a p2p stream. It looks like the solution is to have the publisher to call:
send("|RtmpSampleAccess", true, true)
on the NetStream object _before_ the subscriber calls NetStream.play(), in order to give the permission to subscribers for audio and video streams.
In lccs library, the above permission authorisation happens in WebcamPublisher:
protected function onNetStatus(p_evt:NetStatusEvent):void
if (p_evt.info.code=="NetStream.Connect.Success") {
setTimeout(sendSnapShotPermission, 500);
_stream.send("|RtmpSampleAccess", true, true);
protected function sendSnapShotPermission():void
_stream.send("|RtmpSampleAccess", true, true);
but it doesn't help the problem. In fact, it is not clear to me when this 'snap shot permission' is sent to the subscriber.
One more note: This is not a critisism for the lccs development quality, but rather a question on how ready lccs is for production use. After encountering this bug, I had to go through the lccs code (the open source parts), and found out that the library is not really written, well, carefully, and it is full of temporary quick-n-dirty fixes.
For instance in the above example, sendSnapShotPermission() is called after 500 milliseconds, probably to allow something to happen before calling the method, but how can you be sure that it will happen in 500 milliseconds? Probably,an event listener should have been used. Immediately in the next line, we see:
_stream.send("|RtmpSampleAccess", true, true);
which is a duplicate of sendSnapShotPermission(). many examples like this can be found throughout the library.

Hi Nigel,
Two questions:
1. When the publisher sends the access permission to the subcriber by:
netStream.send("|RtmpSampleAccess", true, true)
, on the subscriber side, what event or function can handle the guaranteed receipt of the access permission? Currently it is possible to draw the incoming stream video upon receiving NetStream.Play.Star and waiting for 5 seconds or so:
public class MyWebcamSubscriber extends WebcamSubscriber {
override protected function layoutCameraStreams():void
// trying the event listener seems to work here.
_streamManager.addEventListener(NetStatusEvent.NET_STATUS, onNetStatus);
override protected function onNetStatus(e:NetStatusEvent):void
super.onNetStatus(e);
case "NetStream.Play.Start":
setTimeout(function():void {
// draw the video from the incoming stream here.
}, 5000);
The questions is, which event can let the subscriber know that it has the access permission to the video stream?
2. In WebcamPublisher, why is that the access permission is sent 3 times?
a. Once on receiving NetStream.Connect.Success with 0.5 second delay, as in below.
b. Once immediately upon receiving NetStream.Connect.Success, as in below.
protected function onNetStatus(p_evt:NetStatusEvent):void
if (p_evt.info.code=="NetStream.Connect.Success") {
setTimeout(sendSnapShotPermission, 500);
_stream.send("|RtmpSampleAccess", true, true);
protected function sendSnapShotPermission():void
_stream.send("|RtmpSampleAccess", true, true);
c. Once in onConnectionTypeChange() with 2 seconds delay:
protected function onConnectionTypeChange(p_evt:StreamEvent):void
if ( _streamManager.isP2P) {
_stream= new NetStream(_connectSession.sessionInternals.session_internal::connection as NetConnection,NetStream.DIRECT_CONNECTIONS);
setTimeout(sendSnapShotPermission, 2000);

Can bypass the phones security even if do not know the lock pattern. Plz fix this bug

Hi,
We can bypass the phone secuity lock even if i do not know the unlock patter or lock password.
Lock the phone. On the Lock screen drag down the notification screen. You have the settings icon on the notification screen. Tap on that and here you go , you can access anyone's phone even if u do know know his/her lock password.
Sony Plz FIX this bug.

Hi sammy3773
I tested all Security locks and the case you write about only happens if you have the slide to unlock feature. (Slide to unlock only protects against accidental touchpad activation but it's not a security lock)
If you set a pattern, a pin, a password, or face Unlock the Notification bar does not slide down.
(Im using ICS 4.0.4)
Best regards
Francis.

When password security-setting dialogue box is opened, the bottom can't be seen or moved

Using Acrobat XI Pro on my Dell PC, I was trying to add password protection to the document. When I click on the "encrypt with password" button, the password security-setting dialogue box pops up, and I can enter the password. However, the bottom of the page is not visible and I can't move it to click the "ok" button. Any suggestions?

Which Acrobat XI Pro are you using? I think you experience the same problem that was reported on this forum in the past. I believe this problem was fixed in one of the recent versions (11.0.07??). Upgrade to the latest version and the problem should go away.

Downloaded file won't open when password-secured

Since moving from Acrobat 8 to 9, my passworded pdf file will not open once it is downloaded from the server. My file was created as an .xls file in openoffice, then converted to pdf. Password security was then set in Acrobat 9 pro (mac). I works fine when not passworded. Is there something I can do to regain the security functionality? Note: the problem only occurs AFTER uploading to the server; it works as it should on my computer before that.

Thanks - I tried do that but I didn't see any appropriate forum - the choices were too specific. Any chance you could point me to the correct one to deal with this issue?

Password security - set permissions for different users

I am using Abobe Acrobat 9 Pro.
In the HELP menu, there is a security section in the contents, In the overview, it states the following:
"Each security method offers a different set of benefits. However, they all allow you to specify encryption algorithms, select the document components to encrypt, and set permissions for different users."
I would like to know how you can set permissions for different users using Password Security.
I am the only one in the company who has Acrobat 9 Pro and all others have Adobe Reader 8.
I have created a PDF file in Acrobat 9, this file is accessible to anyone with Abobe Reader. I would like to set different permissions for different users. For example, i would like certain individuals to print the document and other individuals to not be allowed to print. Can this be acheived using Password Security?
Many Thanks

Password Security gets lost in portfolio/Low definition printing

Using Acrobat Pro Extended 9.0.0, I created a portfolio and added two PDF files to it (these files were not themselves password protected).
I then used File / Portfolio Properties / Security to apply password security, Encrypt except metadata, open password, permissions password allowing High Resolution printing and no changes finally allowing copying of text.
After completion, I then saved the file and closed acrobat.
Then clicked on secured file to open acrobat and was correctly asked for the opening password.
I then changed to list view, clicked on a file, Saved file from portfolio and saved it.
Clicked on PDF document (within portfolio) and looked at Portfolio properties and the security settings were still displayed.
Clicked on OPEN button (top right) and the document was opened. Document Properties still show security set.
Closed acrobat completely.
Clicked on saved document from portfolio and was surprised to find no security settings at all. No opening password, no password for changing document, completely open.
This is a major security hole from what I can see.
Another similar problem. If I secure a PDF document with password security as above, yet with low resolution printing. I can then reopen the secured document and print to an Adobe printer driver creating a new unsecured PDF from my secured document.
I cannot believe Adobe could leave two such wide security holes in Acrobat 9 so surely I am missing something here.
Can someone please tell me how to put together a portfolio without these massive security problems.
Regards
John

Assigning security to a portfolio will not assign security to the individual documents.

PDF password security greyed out while saving a PDF MP Navigator

Hello,
I am unable to set a password for pdf's that I scan with MP Navigator. I have been doing it for years, but now it has greyed out. It is not selectable. I recently upgraded my mobo and did a clean reinstall. The problem occurred before the upgrade and now remains despite full reinstalls of everything. The preferences button provides no way to turn passwords on or off. The Set... button shows password security also greyed out.
Win 7 Home premium 64 bit, 8GB, 250GB SSD root drive, Core i7. MP navigator EX 5.1. Pixma MP 895.
Thanks,
Jim

A simple way is to flatten the form fields, which converts the field appearances to regular page contents. You can do this with JavaScript or PDF Optimizer (Advanced > PDF Optimizer > Discard Objects > Flatten form fields). A very nice script that adds a custom menu item can be found here: http://www.uvsar.com/projects/acrobat/flattener/

PDF Not So Secure!?! Software available to modify or remove privilege password security!?!

Hi, I have searched on the web and have encountered an disturbing new.
This site explains the flaw with PDF security:
http://www.cs.cmu.edu/~dst/Adobe/Gallery/PDFsecurity.pdf
The following site claims that they can remove password security embeded in PDF files that prevents people from modifying or copying information within seconds:
http://www.elcomsoft.com/apdfpr.html
Is it still true for the latest version of Acrobat Professional?
If it is true, I think there is nothing protecting my intellectual property.
Is there some other ways I can make sure that they can only view, print, but not modify or copy the contents in my PDF files?
Adobe staffs, please take a look at this closely.

Did you see the warning that you get when setting security in Acrobat?
In Acrobat 8, "All Adobe products enforce the restrictions set by the
Permissions Password. However, not all third party products fully
support and respect these settings. Recipients using such third-party
products might be able to bypass some of the restrictions you set".
So, while disturbing, this isn't really news.
But in any case, Acrobat's password security does nothing really to
protect you from copying. Any file can be copied or shared. If you
want to protect your intellectual property, you have to enter the
controversial and often expensive world of DRM.

Extensions like Ghostery, WOT or AdBlock stop working after two or three times. Restarting the webpage in a new tab the extensions will work again for several times and then stop again. Has anybody an explanation or a workaround for this bug in Safari 5?

Remove the extensions, redownload Safari, reload the extensions.

Firefox's "NoScript" will block the Trojan going around on websites. Best web security you can get.
