Prior to 0.62.4, an authenticated SSH client can cause a denial of service by sending a pty-req channel request with more than 130 terminal-mode records. The parser in russh/src/server/encrypted.rs stores terminal modes in a fixed 130-entry [(Pty::TTY_OP_END, 0); 130] array but continues increasing the mode count, then constructs an out-of-bounds slice and panics before the application pty_request handler runs. The panic terminates the server session task without causing memory corruption. This issue is fixed in version 0.62.4.","state":0,"publishedAt":"2026-08-13T22:04:44.47+00:00","modifiedAt":"2026-08-17T19:50:33.126+00:00","affected":[{"ecosystem":"Vendor product","name":"russh","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"Eugeny\",\n                    \"product\": \"russh\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 0.62.4\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:L","score":4.3,"severity":"MEDIUM"}],"references":["https://github.com/Eugeny/russh/security/advisories/GHSA-cqjc-rmpq-xprq","https://github.com/Eugeny/russh/commit/8912512371820167a12a0a638bd666856ce458ad","https://github.com/Eugeny/russh/releases/tag/v0.62.4"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-73489","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-73489","identifiers":["CVE-2026-73489"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
