So, the testcase doesn't work for me on my debug build. I get "Setting a property that only has a getter" because the navigator property is supposed to be read only! This patch should work anyway.

Dan, is that testcase really for this bug?
The first one isn't going to work loaded from bugzilla... I didn't seem to need the refresh to reproduce, but if you can't save this attachment and the exp_loader one locally and load it from there.

So loading the mail exploit itself seems to just crash, locally I do need to load the loader page first to get the exploit to run correctly. Here's an attempt to do just that on BMO.

Doesn't seem to work (launch calc.exe) on a known broken version. Still get the crash, but for full effect download attachments 226717 and 226722 locally.
So Firefox 1.0 and mozilla 1.7 are not vulnerable because bug 246224 ("Mozilla crashes if a chrome app uses Live Connect") was fixed on those branches by removing the only call to ProxyFindClass http://bonsai.mozilla.org/cvsblame.cgi?file=mozilla/modules/oji/src/ProxyJNI.cpp&rev=188.8.131.52&mark=322,325,328#315
Comment on attachment 226691 [details] [diff] [review] Fix That should do nicely, r=dveditz You mention this bug didn't happen to you on the trunk because navigator can't be overridden. I'm not seeing that, I crash. This should land on the trunk regardless: either it fixes the crash, or *will* fix it if the readonly attribute stops being enforced again.

I can't believe I missed this before: the liveconnect code checks for JSVAL_IS_OBJECT and if that tests true, then it passes the jsval (as a JSObject *) to JS_GetPrivate. Unfortunately, null is an object, and JS_GetPrivate is not null-safe.
