Attackers can exploit the stun_init_error_response_common_str() function in src/client/ns_turn_msg.c, which fails to zero-initialize the avalue buffer before computing its length with strlen() and copying leaked stack bytes into the ERROR-CODE reason phrase, exposing pointer fragments that weaken ASLR and enable precise version fingerprinting.","state":0,"publishedAt":"2026-10-07T14:29:45.615+00:00","modifiedAt":"2026-10-27T01:30:33.12+00:00","affected":[{"ecosystem":"Vendor product","name":"coturn","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"defaultStatus\": \"unaffected\",\n                    \"vendor\": \"coturn\",\n                    \"product\": \"coturn\",\n                    \"packageURL\": \"pkg:github/coturn/coturn\",\n                    \"repo\": \"https://github.com/coturn/coturn\",\n                    \"versions\": [\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"4.10.0\",\n                            \"versionType\": \"semver\",\n                            \"lessThan\": \"4.11.0\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N","score":6.9,"severity":"MEDIUM"},{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N","score":5.3,"severity":"MEDIUM"}],"references":["https://github.com/coturn/coturn/releases/tag/4.11.0","https://github.com/coturn/coturn/pull/1878","https://github.com/coturn/coturn/commit/741b2983cc52f967dd08c438fd72a5f08f13ca27"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-104074","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-104074","identifiers":["CVE-2026-104074"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
