In go-libp2p, by using signed peer records a malicious actor can store an arbitrary amount of data in a remote node\u2019s memory. This memory does not get garbage collected and so the victim can run out of memory and crash. If users of go-libp2p in production are not monitoring memory consumption over time, it could be a silent attack i.e. the attacker could bring down nodes over a period of time (how long depends on the node resources i.e. a go-libp2p node on a virtual server with 4 gb of memory takes about 90 sec to bring down; on a larger server, it might take a bit longer.) This issue was patched in version 0.27.4."}], "lastModified": "2023-09-01T13:10:55.577", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:protocol:libp2p:*:*:*:*:*:go:*:*", "vulnerable": true, "matchCriteriaId": "C5F4582C-9B6B-41FB-99E1-C3B2CB0E19AD", "versionEndExcluding": "0.27.4"}], "operator": "OR"}]}], "sourceIdentifier": "security-advisories@github.com"}
