Subject: CVE Request : Libtorrent 1.1.0 inflate_gzip denial of service

Hi list,

I recently opened a bug on "Libtorrent 1.1.0" regarding malformed GZIP
encoded responses that causes  denial of service.

For example, an attacker-controlled torrent tracker can crash victim torrent 
clients by sending malformed GZIP responses.

This bug has been fixed by the maintainer in master and the branch RC_1_1:

I also tested the bug with two "Libtorrent based" softwares :
qBittorrent and Deluge. Both of them were affected and crashed on
receiving the malformed response.
