From 0.2.0 until 0.2.5, PageantStream::new in pageant/src/wmmessage.rs trusts a peer-controlled four-byte length prefix and buffers until len + 4 bytes are available without checking the fixed _AGENT_MAX_MSGLEN transport capacity. An application that bridges an SSH forwarded-agent channel to the raw stream can allow a malicious server to force large allocations or retain a partially filled frame, causing client memory exhaustion. This issue is fixed in version 0.2.5.","categories":["Unclassified"],"product":"russh","vendor":"Eugeny","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-116775","source_modified_at":"2026-10-27T20:27:30.852Z","fetched_at":"2026-10-27T21:14:11.489891Z","product":"russh","vendor":"Eugeny","versions":[{"version":">= 0.2.0, < 0.2.5","status":"affected"}],"defaultStatus":null}],"fixed_versions":[],"cvss":2.3,"severity":"Low","kev":{"listed":false},"epss":{"probability":null,"percentile":null,"score_date":null},"published_at":"2026-10-27T20:27:30.852Z","modified_at":"2026-10-27T20:27:30.852Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-116775","fetched_at":"2026-10-27T21:14:11.489891Z","source_modified_at":"2026-10-27T20:27:30.852Z"}],"sources":["CVE List"],"references":[{"source":"CVE List","url":"https://github.com/Eugeny/russh/security/advisories/GHSA-662x-8wvj-2276","tags":["x_refsource_CONFIRM"]},{"source":"CVE List","url":"https://github.com/Eugeny/russh/commit/69e4b55513eaa8ac9d2ad4236f13171fc164e10a","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/Eugeny/russh/releases/tag/v0.65.0","tags":["x_refsource_MISC"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-27T20:27:30.852Z","content_hash":"4b173d1db6ef4611739c64d81a0505c7ded287cd7961cfc5fa430ef7f016c883"}}
