1248577 - Firefox silently fails to decode more than 16 nested Content-Encoding: gzip,gzip...

Status: UNCONFIRMED

(Core :: Networking: HTTP, defect, P5)

Description

[WGH]

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:38.0) Gecko/20100101 Firefox/38.0
Build ID: 20160207155849

Steps to reproduce:

http://a-raspberry-pi-among-the-flower-pots.torlan.ru/hello.gz.gz.gz.gz.gz.gz.gz.gz.gz.gz.gz.gz.gz.gz.gz.gz
http://a-raspberry-pi-among-the-flower-pots.torlan.ru/hello.gz.gz.gz.gz.gz.gz.gz.gz.gz.gz.gz.gz.gz.gz.gz.gz.gz

The server sends "Hello world" string encoded with gzip multiple times.
Content-Encoding is set to "gzip,gzip,gzip,..." (appropriate number of times).


Actual results:

The first link opens fine. The second one displays garbage.


Expected results:

I do admit that there should be sensible limit for nested Content-Encodings, however, Firefox should display a error message instead of returning garbage to the user.
