Bitcoin Optech Newsletter #425

This week's Bitcoin Optech Newsletter #425 highlights two critical denial-of-service (DoS) vulnerabilities affecting older versions of Eclair (v0.13.1 and earlier), which have since been fixed in v0.14.0. The first vulnerability stemmed from inefficient feature bit parsing, where a single maximum-length init message could allocate 300 MB of memory and occupy a parsing thread for 300 ms, enabling attackers to quickly disconnect peers and exhaust memory. This was discovered using the `smite` LN fuzzer. The second DoS flaw was in gossip queries, where zlib decompression of legacy `query_short_channel_ids` messages lacked an output limit, allowing a 64 KB message to expand to 64 MB, potentially taking nodes offline. Both attacks required only a BOLT8 handshake. The newsletter also outlines a proposal for secure wallet label synchronization across devices and regular updates on Bitcoin consensus rule discussions and infrastructure software changes.

Bitcoin think tank questions MSCI’s ‘invisible committee’ over Strategy, Metaplanet rule

A paper from the Bitcoin Policy Institute (BPI) has raised concerns about a proposed rule by MSCI, a global index provider. The BPI argues that MSCI's "non-operating company" rule could lead to the exclusion of prominent Bitcoin-holding companies, such as MicroStrategy (referred to as Strategy) and Metaplanet, from its widely followed indexes. The institute suggests that the origins of this proposed rule might be linked to an earlier review conducted by MSCI concerning corporate crypto treasuries. The potential removal of these companies from major indexes could impact their visibility and attractiveness to institutional investors, affecting the broader perception and integration of Bitcoin into traditional financial structures. This highlights a growing intersection between traditional financial indexing methodologies and the burgeoning trend of companies adopting Bitcoin as a treasury asset.
