A parsing vulnerability in lnd’s onion processing logic and lead to a DoS vector due to excessive memory allocation. The issue was patched in lnd v0.17.0. Users should update to a version > v0.17.0 to be protected. Users unable to upgrade may set the --rejecthtlc
CLI flag and also disable forwarding on channels via the UpdateChanPolicyCommand
, or disable listening on a public network interface via the --nolisten
flag as a mitigation.
