A flaw was found in Rekor. The `Package.Unmarshal()` function, which processes Alpine Package Keep (APK) files, decompresses gzip streams without limiting the total decompressed size. A remote attacker can exploit this by crafting a malicious APK file with a high compression ratio, causing the server to consume excessive memory. This leads to a Denial of Service (DoS) through an out-of-memory (OOM) error, and can be triggered via unauthenticated API endpoints.
