{"id":"DEBIAN-CVE-2026-41678","details":"rust-openssl provides OpenSSL bindings for the Rust programming language.  From  to before 0.10.78, aes::unwrap_key() contains an incorrect assertion: it checks that out.len() + 8 \u003c= in_.len(), but this condition is reversed. The intended invariant is out.len() \u003e= in_.len() - 8, ensuring the output buffer is large enough. Because of the inverted check, the function only accepts buffers at or below the minimum required size and rejects larger ones. If a smaller buffer is provided the function will write past the end of out by in_.len() - 8 - out.len() bytes, causing an out-of-bounds write from a safe public function. This vulnerability is fixed in 0.10.78.","modified":"2026-09-01T16:06:41.964757138Z","published":"2026-04-24T18:16:29.420Z","upstream":["CVE-2026-41678"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-41678"}],"affected":[{"package":{"name":"rust-openssl","ecosystem":"Debian:12","purl":"pkg:deb/debian/rust-openssl?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.10.45-1","0.10.57-1","0.10.64-1","0.10.68-1","0.10.70-1","0.10.72-1","0.10.73-1","0.10.78-1","0.10.79-1","0.10.81-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-41678.json"}},{"package":{"name":"rust-openssl","ecosystem":"Debian:13","purl":"pkg:deb/debian/rust-openssl?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.10.72-1","0.10.73-1","0.10.78-1","0.10.79-1","0.10.81-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-41678.json"}},{"package":{"name":"rust-openssl","ecosystem":"Debian:14","purl":"pkg:deb/debian/rust-openssl?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.10.78-1"}]}],"versions":["0.10.72-1","0.10.73-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-41678.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H"}]}
