| summary: Out-of-memory vulnerability in github.com/libp2p/go-libp2p |
| description: |- |
| A malicious actor can store an arbitrary amount of data in the memory of a |
| remote node by sending the node a message with a signed peer record. Signed peer |
| records from randomly generated peers can be sent by a malicious actor. This |
| memory does not get garbage collected and so the remote node can run out of |
| memory (OOM). |
