Jordi, can you reproduce this with a 4.0 beta build? No crash here...

Comment 4

Firefox 4.0 beta build don't crash.
But multiple crash report have been sent for 3.6.14.



I will retry with 3.6.14

Crash-stats for this stack (see comment 4) look scary exploitable. Have not been able to repro myself, but socorro shows there's a real problem here somewhere.

The crash is very intermittent , go to and wait .
Yeah, I can repro on Linux64 debug but it takes about 30 minutes each time.
GDB tells me this is an optimized image, as in bug 610601.
It's hard to debug because of the setjmp/longjmp error handling...

Not Fixed for 3.6.16?

Let's see if the patch in bug 639303 fixes this.
This doesn't happen _as_much_ in Firefox 4.0, but I do see a couple stacks that are the same as the scary one here.


This is essentially a dupe of bug 557107 but we might as well work on it in this bug that's already appropriately marked and hidden. Also this one links to a testcase that at least the reporter can reproduce with, even if we can't.

> Let's see if the patch in bug 639303 fixes this.

That seems to be a completely different stack and a more reproducible case. In any case it's going to be hard to see if bug 639303 fixes this because even Jordi has trouble reproducing this on mozilla-central nightlies.

The fix in bug 639303 has not landed yet. At this point you'll only be testing how hard it is to reproduce on 4.0.

http://meteoaragon.blogspot.com/ crash sometime more quickly .
bug 639303 landed on 6.0a1 Nightlies last week and in Fx5 ("Aurora") 5/15. Does it still reproduce in a current Aurora build?

Aurora build don't crash. FIXED?
It still crashes on the 1.9.2 branch.  Unfortunately the fix for bug 639303
doesn't apply on 1.9.2 or older.  Let's use this bug to handle 1.9.2 and
older branches and 639303 handle 2.0 and newer.

mats, we need to get this fixed on 1.9.2 ASAP as we will disclose it when we ship Fx5
I tried to reproduce this for about an hour without any crash occurring.  - connection times out
http://www.sdj-airport.com/live/  - connection times out
http://meteoaragon.blogspot.com/  - responds, but is very slow

I don't think it's meaningful for me to work on this bug without
steps to reproduce that will cause crashes.

I reproduced on Mac:


Loading (had to reload a couple of times to get the image to work):

Reproduced on XP SP3 with last night's build within three minutes:


Using http://meteoaragon.blogspot.com
Only thing different Dan and I did was disable the flash plugin to make things not pull in Flash data.
meteoaragon.blogspot.com still crashes for me, takes < 3minutes to cycle through the images and hit the bad one on WinXP
Assignee: nobody → joe
I made a testcase that does multipart/x-mixed-replace on an alternating pair of images. You can only hit it from the MV Office VPN, though:
I haven't observed any crashes with the URL in comment 29, but perhaps the testcase needs to do something more complex than alternate between two images?
This bug qualifies for the security bug bounty

This bug is a duplicate of bug 524921, which we, for unfathomable reasons, thought did not apply to 1.9.2.
