{"id":"DEBIAN-CVE-2026-34155","details":"RAUC controls the update process on embedded Linux systems. Prior to version 1.15.2, RAUC bundles using the 'plain' format exceeding a payload size of 2 GiB cause an integer overflow which results in a signature which covers only the first few bytes of the payload. Given such a bundle with a legitimate signature, an attacker can modify the part of the payload which is not covered by the signature. This issue has been patched in version 1.15.2.","modified":"2026-09-14T17:03:30.508497845Z","published":"2026-03-31T14:16:11.997Z","upstream":["CVE-2026-34155"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-34155"}],"affected":[{"package":{"name":"rauc","ecosystem":"Debian:12","purl":"pkg:deb/debian/rauc?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.10.1-1","1.10.1-2","1.11-1","1.11.3-1","1.11.3-2","1.12-1","1.13-1","1.13-2","1.13-3","1.14-1","1.15-1","1.15.1-1","1.15.2-1","1.8-2","1.9-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-34155.json"}},{"package":{"name":"rauc","ecosystem":"Debian:13","purl":"pkg:deb/debian/rauc?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.13-3+deb13u1"}]}],"versions":["1.13-3"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-34155.json"}},{"package":{"name":"rauc","ecosystem":"Debian:14","purl":"pkg:deb/debian/rauc?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.15.2-1"}]}],"versions":["1.13-3","1.14-1","1.15-1","1.15.1-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-34155.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N"}]}
