Second Critical LND Bug in Less Than a Month Causes LND Nodes to Fall Out of Sync with Chain Again

• Only impacts LND nodes, other lightning implementations are still in sync.
• LND team is working on a fix that should be released shortly.
• Nodes can still make and route payments, but are not aware of current chain state until updated.
• Nodes that do not update will be vulnerable to malicious channel closes by peers they have channels with once their channel timelocks expire.
• The default timelock is two weeks.
• Bug was triggered by same dev that triggered the last sync issue.
• Message in transaction said: "you'll run cln. and you'll be happy."
• Some versions of electrs seem to be impacted as well.
• Anthony Towns claims he disclosed this bug to LND devs two weeks ago.
• An update has been released that patches this issue.
