65065 - Dragging a large selection into the browser disables entering URLs from the keyboard

Status: RESOLVED INCOMPLETE

(Core :: Networking, defect)

Description

[Gunnar Wolf]

When a large amount of text is selected and the middle mouse button is dragged
within the main area of the window (not only the URL entry area), Mozilla tries
to open the URL specified by the whole text. It is not legal, of course, and in
the console where I opened Mozilla I get the following data:

Error loading URL
http:///%5BAs%20an%20owner%20of%20Red%20Hat%20Linux%206.1%20you%20are%20entitled%20to%20any%20or%20all%20of%20the%20following%20benefits:%5D%5Bpriority%20ftp%20access%5DNo%20more%20late-night%20visits%20to%20congested%20mirror%20sites!%20As%20a%20Red%20Hat%20Linux%206.1%20owner,%20you%20are%20eligible%20for%20free%20access%20to%20priority.redhat.com,%20our%20preferred%20customer%20FTP%20service,%20offering%20high%20bandwidth%20connections%20day%20and%20night.%5Bofficial%20red%20hat%20support%5DRed%20Hat%20Linux%206.1%20owners%20are%20en
(...)

After this, when entering a URL by hand (http://www.unam.mx), I got the
following response:

Error loading URL
http:///www.unam.mxNo%20more%20late-night%20visits%20to%20congested%20mirror%20sites!%20As%20a%20Red%20Hat%20Linux%206.1%20owner,%20you%20are%20eligible%20for%20free%20access%20to%20priority.redhat.com,%20our%20preferred%20customer%20FTP%20service,%20offering%20high%20bandwidth%20connections%20day%20and%20night.%5Bofficial%20red%20hat%20support%5DRed%20Hat%20Linux%206.1%20owners%20are%20entitled%20to%2090%20days%20of%20installation%20web%20support.%20Owners%

It seems to be a buffer overflow in the URL parsing.

Wait a minute-isn't this behavior *exactly* what is to be expected of the middle 
button?

Comment 5

[Gunnar Wolf]

Dan: No. I mean, yes, the browser should try to load the text you send to it and treat it as if it were a URL; however, if you check my report, you will see it seems like a buffer overflow when presented with too much text.

Do you have a legitimate URL that is long?  I don't think its reasonable to 
expect Mozilla to hold about 5K of text in the URL field...no?

Assuming this is a buffer overflow problem with the URL parsing, reassigning to
networking. This might be a clibboard or editor or drag/drop or UI backend or
form controls problem as well. ;)

Comment 9

[Gunnar Wolf]

Dan: No, I do not have a legitimate URL causing this. However, the bug is still there - What if in my page I put a bogus, incredibly long URL that will block correct operation of your browser? It should be fixed, IMHO...

Does the problem still occur in a recent Firefox trunk build?

If so, please attach a plain text file containing the text you
paste into the URL bar so we can reproduce the problem. Thanks.
