- Summary
- github.com/ipfs/kubo affected by DOS Bitswap unbounded persistent memory leak
- Details
-
Impact
An attacker is able allocate arbitrarily many bytes in the Bitswap server by sending many
WANT_BLOCKand orWANT_HAVErequests which are queued in an unbounded queue, with allocations that persist even if the connection is closed.This affects users accepting or connecting untrusted connections such as by running in the public swarm and no pnet config. Nodes that are not publicly reachable but connects to untrusted nodes are also vulnerable to the untrusted nodes being connected to since libp2p connections are blindly bidirectional.
Patches
- 19feb15833c6f4d6e7f1e1b132efaae96d76481d
boxoupdate in Kubo - GHSA-m974-xj4j-7qv5 patches in boxo
Workarounds
Use PNET, swarm filters or resource manager allows list to block untrusted connections.
Note that using the resource manager will disrupt both client and server features because the bitswap protocol is a message based protocol mixing requests and responses.
