99477 - Mozilla for Mac OS X crashes Filemaker Pro 5.5 on Mac OS 9

Status: VERIFIED WONTFIX

(Tech Evangelism Graveyard :: English US, defect)

Description

[Joseph Delaney]

From Bugzilla Helper:
User-Agent: Mozilla/5.0 (Macintosh; U; PPC Mac OS X; en-US; rv:0.9.4+)
Gecko/20010911
BuildID:    2001091121

We rely on the URL given to function, and since Mozilla locks it solid, please
contact me before trying it so I can stand by to restart it. 

When any type of request for a page is sent from Mozilla for MacOS X to
Filemaker Pro for MacOS 9, Filemaker Pro locks up and has to be manually
restarted (using a "Force Quit" and sometimes corrupting the databases).  

Reproducible: Always
Steps to Reproduce:
Steps to reproduce:
0. Contact me [e-mail] and agree on a time so I can restart the
server (I have to be in the room to do the three-finger salute)
1. Go to http://TeachX.rutgers.edu/ecs/ using Mozilla for MacOS X,
"Fizilla"(there is a javascript that will redirect you, so turn off javascript
first - I will remove this once we move our databases to another server). Even
better, set up your own Filemaker Pro 5.5 database running on MacOS 9.1, and
turn on sharing through the "Web Companion" and crash your own machine. :-)
2. Do a search or click the link for "All Enhanced Rooms"



Actual Results:  Nothing. Mozilla will wait patiently for a response, however it
will never receive one because Filemaker Pro 5.5 has crashed and needs to be
restarted.


Expected Results:  You should see the search results without crashing the server.

I have reproduced this on two separate Mac OS X machines (a G4 running Mozilla
20001091121 and a G3 running several earlier builds of 0.9.3)

It does not matter if you submit a form using POST or follow a link, any attempt
at all to access a web page served by Filemaker Pro 5.5 for MacOS 9 crashes
Filemaker Pro. 

Only Fizilla seems to be affected. The problem does not occur with Mozilla 0.9.3
for Windows 98 or with Netscape 6.1 for Windows 98.  I am reporting the problem
simultaneously to Filemaker where it really needs to be fixed as a Denial of
Service vulnerability.

Reporter, please double-check that Fizzilla build ID of 2001091121. There is no Mac OS X 
build in [http://ftp.mozilla.org/pub/mozilla/nightly/2001-09-11-21-trunk/].

It definitely says "2001091121" in the title bar. The "About Mozilla" page is
missing the final two digits, and the "Get Info" box shows a creation date of
"Sep 11, 2001, 11:18 PM"

However, there is something under

http://ftp.mozilla.org/pub/mozilla/nightly/2001-09-11-20-trunk/

Reporter, try making a minimal (but still valid and well-formed) HTML page and see if it still 
crashes. Also, try accessing a file of type other than HTML and see if it still happens.

Also, try at least one other Mac OS X browser.

Attachment: Very simple HTML document

Comment 5

[Joseph Delaney]

Neither Omniweb 4.03 or Internet Explorer 5.1.1 Preview trigger the crash.

Pointing Mozilla to a very simple HTML document (attached) still causes
Filemaker Pro to crash, as does pointing it to  a gif.

sdagley, pink, smfr, can one of you look at this?

Comment 7

[Steve Dagley]

As I read this bug the Mac that crashes is the server running FMpro, not the Mac 
running Mozilla.  Smacks of a buffer overflow problem.  That's really an issue 
for Claris (or do they just call themseles Filemaker these days?  And when did 
FMpro become a web server?) to solve.  Since AFAIK nobody here has FMPro it's not 
like we've got much chance of debugging w/o jpd sitting there as we repeatedly 
crash his server.  if somebody can come up with a contact at Claris/Filemaker I'd 
be happy to help them debug this.

One thing to do here would be to run Interarchy's Traffic Watching feature on 
either the machine sending the request, or on the machine running FileMaker, and 
compare traffic for the Fizilla and non-Fizilla queries.

I really think this is a problem at the FileMaker end; it shouldn't crash, even 
if the browser sends garbage.

Comment 10

[Greg K.]

Confirmed using Fizzilla/2001091313 (0.9.4). Accessing
[http://picard2.rutgers.edu/test.html] causes the server to crash. Accessing the
same URL with Mac IE 5.1b1 (3408) for OS X does not cause a crash.

We need to see what data is being received by FileMaker. Can we arrange to run 
Interarchy with traffic watching on the FileMaker machine?

This appears to be a problem with FileMaker Pro and the "Accept-Encoding:" 
header. 4.x sends

Accept-Encoding: gzip

and Mozilla sends:

Accept-Encoding: gzip, deflate, compress;q=0.9

If I change the Mozilla networking prefs to send "gzip", it doesn't crash. BTW, I 
saw the crash with classic builds of Mozilla.

Full headers (from stream transcript):

This is definately a FM Pro bug, and there is a workaround (set the "Accept-
Encoding" pref in Mozilla). There is nothing we can do to fix this.

Comment 16

[Steve Dagley]

Changing OS from Mac OS X cause it clutters up my query.  I'd change other fields 
but there doesn't seem to be a FileMaker component in Bugzilla :-)

I am informed that this bug has been cured by the filemaker web companion 5.5v3
