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.
AnalysisAI
Integer overflow in RAUC versions prior to 1.15.2 allows signature bypass on 'plain' format bundles exceeding 2 GiB payload size, enabling attackers with bundle modification capability to alter unverified payload portions while retaining a valid signature. This affects embedded Linux systems relying on RAUC for secure firmware updates.
