Vulnerabilities Disclosures

  • 00:17:51 “Linux being secure is a common misconception in the security and privacy realm. Linux is thought to be secure primarily because of its source model, popular usage in servers, small userbase and confusion about its security features.” [madaidans-insecurities]
  • 00:19:50 Public disclosure of a block stalling bug in Bitcoin Core affecting LN:
    • Eugene Siegel disclosed responsibly a vulnerability he had responsibly disclosed almost three years ago, which could potentially facilitate fund theft from Lightning routing nodes. The vulnerability entails an attacker causing substantial delays in block propagation towards a Bitcoin Core node utilized by a Lightning node. This delay is sufficient to intercept an in-flight payment routed through the victim’s node, enabling the attacker to pilfer its value.
    • During the initial phase, the attacker gains control of all high-bandwidth compact block relay slots belonging to the victim, achieving this by consistently delivering blocks faster than any other peers. The attacker then proceeds to deceive the victim regarding new block arrivals. This deception involves announcing the header of a new block on one of the controlled connections but withholding the actual block. In versions of Bitcoin Core preceding 22.0, the software will wait up to 10 minutes before seeking the block from an alternative connection. Exploiting this delay, the attacker, with around 50 malicious connections, can effectively conceal new blocks from the victim for a period surpassing the 40-block interval between two in-flight HTLCs within the routed payment.
    • Bitcoin Core 22 and higher contain fixes for the bug, but many people are still running affected versions and some of those users might also be running LN implementations or other contract protocol software that could be vulnerable to exploitation of the bug.
    • It is believed no one has lost funds due to the attack.

    • The invitees can be added/removed at will by the owner of the document.
    • The users send ephemeral events while live editing and can hit “save” to propose a new version of the document.
    • Everybody sees what the others are doing in real time
    • The document’s owner chooses which version to make “official”.
    • Documents can be forked so any of the invitees (or anybody else if the document is allowed to be public) can fork the document and continue working on their own version.

    • Ideas for relay enhancements after cluster mempool is deployed:
    • Gregory Sanders posted to Delving Bitcoin presenting several ideas for enabling individual transactions to opt-in to specific mempool policies after cluster mempool support has been fully implemented, tested, and deployed.
    • These enhancements leverage the capabilities of v3 transaction relay by relaxing some of its rules that may become unnecessary and introducing a requirement for a transaction (or a package of transactions) to pay a feerate ensuring their likelihood of being mined within the next block or two.
  • What would have happened if v3 semantics had been applied to anchor outputs a year ago:
    • Suhas Daftuar posted to Delving Bitcoin regarding his research on automatically applying v3 transaction relay policy to anchors-style LN commitment and fee-bumping transactions.
    • Out of 14,124 transactions recorded in 2023 resembling anchor spends:
    • About 94% would have been successful under the v3 rules.
    • Approximately 2.1% had more than one parent, necessitating adjustments in LN wallet behavior.
    • Around 1.8% were not the first child of the parent, affecting package relay proposals.
    • About 1.2% were apparently grandchildren of the commitment transaction, posing challenges for LN wallet behavior.
    • Approximately 1.2% were never mined and weren’t analyzed further.
    • Less than 0.1% spent an unrelated unconfirmed output, requiring automatic resolution.
    • Less than 0.1% were larger than 1,000 vbytes, suggesting a potential adjustment in v3 size limits.
    • Additional discussion and research are anticipated, indicating that LN wallets might require minor adjustments to align with v3 semantics before Bitcoin Core could safely treat anchor spends as v3 transactions.
  • 288
    • Securely opening zero-conf channels with v3 transactions:
    • Matt Corallo posted to Delving Bitcoin to discuss securely allowing zero-conf channel opening with the proposed v3 transaction relay policy.
    • Zero-conf channel opens involve new single-funded channels where the funder gives some or all of their initial funds to the acceptor. These funds are not secure until the channel open transaction receives a sufficient number of confirmations, eliminating the risk of the acceptor spending those funds back through the funder using the standard LN protocol.
    • The initial proposal for v3 transaction relay policy would only allow an unconfirmed v3 transaction to have, at most, a single child in the mempool, with the expectation that the single child will CPFP fee bump its parent if necessary.
    • These v3 rules pose challenges for fee bumping zero-conf channel opens, as the funding transaction creating the channel is the parent of a v3 transaction closing the channel and the grandparent of a v3 transaction for fee bumping. With v3 rules only permitting one parent and one child, fee-bumping the funding transaction without modification is not feasible.
    • Proposed solutions include modifying funding and splicing transactions to include an extra output for CPFP fee bumping, awaiting advancements in cluster mempool to potentially permit more permissive topologies, and then transitioning to using a more permissive topology by dropping the extra output.
    • Requirement to verify inputs use Segwit in protocols vulnerable to txid malleability:
    • Bastien Teinturier posted to Delving Bitcoin to highlight a crucial requirement for protocols where a third party contributes an input to a transaction that must maintain its txid after another user contributes a signature.
    • In scenarios like LN dual-funded channels, both parties contribute inputs to ensure each receives a refund if the other fails to cooperate later.
    • Segwit prevents txid malleability, but for segwit v0, Alice must verify that Bob is spending a segwit v0 output by obtaining a copy of the entire previous transaction containing Bob’s output to prevent potential malleability.
    • For segwit v1 (Taproot), each SIGHASH_ALL signature directly commits to every previous output being spent in the transaction, allowing Alice to verify Bob’s scriptPubKey and ensure it uses segwit, thus preventing malleability.
    • Protocols relying on presigned refunds must adhere to two security rules:
      1. If contributing an input, prefer to contribute an input that spends a segwit v1 output, verify previous outputs of all other spends, ensure they use segwit scriptPubKeys, and commit to them using your signature.
      2. If not contributing an input or not spending a segwit v1 output, obtain complete previous transactions for all inputs, verify their outputs being spent are all segwit outputs, and commit to those transactions using your signature.
    • Proposal for replace by feerate to escape pinning:
    • Peter Todd posted to the Bitcoin-Dev mailing list a proposal for a set of transaction replacement policies usable when existing replace-by-fee (RBF) policies won’t allow a transaction to be replaced, coming in two variations:
      1. Pure replace by feerate (pure RBFr): Allows a transaction in a mempool to be replaced by a conflicting transaction paying a significantly higher feerate (e.g., 2x the replacee’s feerate).
      2. One-shot replace by feerate (one-shot RBFr): Permits a transaction in a mempool to be replaced by a conflicting transaction paying a slightly higher feerate (e.g., 1.25x), provided the replacement’s feerate is high enough to rank it in the top ~1,000,000 vbytes of the mempool.
    • Mark Erhardt highlighted potential abuse of the proposed policies, prompting adjustments from Peter Todd to address such concerns.
    • Additional concerns were raised by Gregory Sanders and Gloria Zhao regarding the complexity and feasibility of implementing these policies accurately and their impact on free relay protection.
    • As of this writing, the separate discussions remain unresolved. Peter Todd has released an experimental implementation of the replace by feerate rules.

Privacy

  • 1:28:28 Apple PWA ban Announcement
    • Last week, iPhone users in the European Union noticed that they were no longer able to install and run web apps on their iPhone’s Home Screen in iOS 17.4.
    • Apple explains that it would have to build an “entirely new integration architecture that does not currently exist in iOS” to address the “complex security and privacy concerns associated with web apps using alternative browser engines.”
    • The Digital Markets Act requires that all browsers have equality, meaning that Apple can’t favor Safari and WebKit over third-party browser engines. Therefore, because it can’t offer Home Screen web apps support for third-party browsers, it also can’t offer support via Safari.

  • 1:30:39 Matt Corallo proposes a BIP which resolves human readable names into payment info
    • “User behavior has clearly indicated a strong demand for the resolution of human-readable names into payment instructions. This BIP defines a protocol to do so using only the DNS, providing for the ability to query such resolutions privately, while utilizing DNSSEC to provide compact and simple to verify proofs of mappings.
    • I’d like to hereby request a BIP number assignment. What is the current approach to do so - since the mailing list has died, is a post on delving bitcoin the appropriate place to publish BIP drafts?” - @TheBlueMatt
