{"id":"CVE-2026-34155","summary":"RAUC: Improper Signing of Plain Bundles Exceeding 2 GiB","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.","aliases":["GHSA-6hj7-q844-m2hx"],"modified":"2026-04-10T05:43:20.362109Z","published":"2026-03-31T13:28:14.863Z","database_specific":{"cna_assigner":"GitHub_M","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/34xxx/CVE-2026-34155.json","cwe_ids":["CWE-196","CWE-347"]},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/34xxx/CVE-2026-34155.json"},{"type":"FIX","url":"https://github.com/rauc/rauc/commit/4fb7c798d6ae412344fb8f8d310d773046af3441"},{"type":"WEB","url":"https://github.com/rauc/rauc/releases/tag/v1.15.2"},{"type":"ADVISORY","url":"https://github.com/rauc/rauc/security/advisories/GHSA-6hj7-q844-m2hx"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-34155"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/rauc/rauc","events":[{"introduced":"0"},{"fixed":"4fb7c798d6ae412344fb8f8d310d773046af3441"}],"database_specific":{"versions":[{"introduced":"0"},{"fixed":"1.15.2"}]}}],"versions":["v0","v0.1","v0.1.1","v0.2","v0.3","v0.4","v1.0","v1.0-rc1","v1.1","v1.10","v1.10.1","v1.11","v1.11.1","v1.12","v1.13","v1.14","v1.15","v1.15.1","v1.2","v1.3","v1.4","v1.5","v1.5.1","v1.6","v1.7","v1.8","v1.9"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-34155.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:P/VC:L/VI:H/VA:N/SC:H/SI:H/SA:H"}]}
