Prior to 0.63.1, a connection configured to permit mac=none can negotiate it with a MAC-requiring CTR or CBC block cipher because the selection logic validates needs_mac() only when MAC selection fails. A remote peer can then send a packet with a decrypted length of zero, causing russh/src/cipher/mod.rs to shrink the previously read block before indexing buffer.buffer[16..], which panics and terminates the connection task. This issue is fixed in version 0.63.1.","state":0,"publishedAt":null,"modifiedAt":null,"affected":[],"metrics":[{"system":"EUVD CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:L","score":3.7,"severity":null}],"references":["https://github.com/Eugeny/russh/security/advisories/GHSA-p8qx-h547-fjw9","https://github.com/Eugeny/russh/commit/2885385abfee279092a41d80c6cb6ac367353159","https://github.com/Eugeny/russh/releases/tag/v0.63.1"],"sourceUrl":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2026-89205","license":"ENISA EUVD · source terms and attribution apply","enrichment":{"sourceStatus":null,"weaknesses":[],"productCriteria":[],"sourceDates":{"datePublished":"Sep 29, 2026, 6:23:28 PM","dateUpdated":"Sep 29, 2026, 7:53:30 PM"},"relatedAdvisories":[],"note":"EUVD source date text has no stated timezone and is retained without inventing a UTC instant.
