Prior to 0.64.1, the agent server spawns a separate long-lived task for every SSH_AGENT_CONSTRAIN_LIFETIME record in a constrained add-key request. The loop accepts repeated lifetime records, clones the key blob into each task, and does not roll back tasks when later constraint parsing fails. An attacker that can speak the agent protocol locally or through agent forwarding can exhaust memory and tasks until the agent process is starved or terminated, denying SSH agent service. This issue is fixed in version 0.64.1.","state":0,"publishedAt":null,"modifiedAt":null,"affected":[],"metrics":[{"system":"EUVD CVSS 3.1","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L","score":4.3,"severity":null}],"references":["https://github.com/Eugeny/russh/security/advisories/GHSA-4wc5-f2rc-q74m","https://github.com/Eugeny/russh/commit/4c305033d72f8e5dd21a3fd4c53a6c291a16ebd1","https://github.com/Eugeny/russh/releases/tag/v0.64.1"],"sourceUrl":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2026-104457","license":"ENISA EUVD · source terms and attribution apply","enrichment":{"sourceStatus":null,"weaknesses":[],"productCriteria":[],"sourceDates":{"datePublished":"Oct 19, 2026, 4:30:24 PM","dateUpdated":"Oct 19, 2026, 6:29:47 PM"},"relatedAdvisories":[{"id":"RHSA-2026:90366","title":"Red Hat Security Advisory: Red Hat Hardened Images RPMs bug fix and enhancement update","vulnerabilityIds":["CVE-2026-111061"]}],"note":"EUVD source date text has no stated timezone and is retained without inventing a UTC instant.
