anacrolix/torrent through 1.61.0 contains a memory exhaustion vulnerability in the tracker/http package that allows malicious trackers to crash clients by returning unbounded responses. Attackers controlling an HTTP tracker in a torrent file or magnet link can return huge or gzip-compressed announce or scrape responses that Client.Announce and Client.Scrape buffer without limits, exhausting process memory.
