Allocation of Resources Without Limits or Throttling
Boxo, formerly known as go-libipfs, is a library for building IPFS applications and implementations. In versions 0.4.0 and 0.5.0, if an attacker is able allocate arbitrary many bytes in the Bitswap server, those allocations are lasting even if the connection is closed. This affects users accepting untrusted connections with the Bitswap server and also affects users using the old API stubs at
github.com/ipfs/go-libipfs/bitswap because users then transitively import
github.com/ipfs/go-libipfs/bitswap/server. Boxo versions 0.6.0 and 0.4.1 contain a patch for this issue. As a workaround, those who are using the stub object at
github.com/ipfs/go-libipfs/bitswap not taking advantage of the features provided by the server can refactor their code to use the new split API that will allow them to run in a client only mode:
All versions starting from 0.4.0 up to 0.5.0
Unfortunately, there is no solution available yet.
