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: https://github.com/arvidn/libtorrent/issues/1021 https://github.com/arvidn/libtorrent/pull/1022 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. Download attachment "0x0443D821.asc" of type "application/pgp-keys" (3114 bytes)
