The lazy_bdecode function in BitTorrent DHT bootstrap server (bootstrap-dht ) allows remote attackers to execute arbitrary code via a crafted packet, related to "improper indexing."
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (5.51%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
