SES Meeting: Deferred Module Exports Plan Interference Hazard
Channel: Agoric
Date: 23/06/2023

Today we met with Nicolò, a champion of deferred module exports to discuss potential reentrancy and plan interference hazards inherent to introducing deferred module exports. The proposal does not introduce a reentrance vector for the read barrier that triggers deferred evaluation since that occurs through property access and there is an expectation that this may cause reentrance already. But we begin to investigate a plan interference attack, for which we need a concrete example and will continue investigating next week.
