Details

Unlimited frames are displayed, until the system memory is "filled with frames" and no memory is left. Possible effects of the bug: - Mozilla crashes - It's not possible to start further programmes, because there is no system memory left - The OS crashes Tested on other browsers: - Netscape Communicator 4.72 is ok - IE 5.5 (preview) is ok Tested on: Win98 SE 128 MB RAM Mozilla build ID: 2000030913 The code: Download as zip file http://stud3.tuwien.ac.at/~e9826090/mozilla/unlimited-frames/unlimited-frames.zip Here is the HTML code: <!-- ----------------- filename: unlimited-frames1.html <html> <head> <title></title> </head> <frameset rows="50%,50%"> <frame src="unlimited-frames-2.html"> <frame src="unlimited-frames-2.html"> </frameset> <body></body> </html> ----------------- filename: unlimited-frames2.html <html> <head> <title></title> </head> <frameset rows="50%,50%"> <frame src="unlimited-frames-1.html"> <frame src="unlimited-frames-1.html"> </frameset> <body></body> </html> ----------------- //--> eof
I got up to 410 webshells and didnt crash on Linux build 2000.03.09.13. But maybe there should be some safeguards, or maximum number of frames. Marking NEW

Why would you intentionally try to crash the browser? ;) This bug is already reported as bug 8065. Thanks! *** This bug has been marked as a duplicate of 8065 ***

Zach, that is good information - what do you think a good limit is? Around 200? 100? I eventually want to fix bug 8065 by putting a limit on the depth of nesting. I think 100 would allow almost all useful websites to be displayed fully but prevent crashes like this.
I tried to crash the browser because I think that the stability of the programme is very important. For sure no webdesigner would create HTML code to crash the browser ? however think of all the ?script kiddies? and ?cyber vandals? who could put this code on their pages on purpose. Furthermore the code could be included in cracked websites. Finally I don?t like the idea that there is a bug which may result in the crash of Mozilla but at the same time M$ IE can handle it. That?s my opinion? ;)
Marking verified dup of 8065.
