Out-of-bounds read via mismatched array lengths
Published Mar 24, 2023 · Updated Feb 19, 2025
Out-of-bounds read in Amazon Web Services Versionize 0.1.1 through 0.1.9 allows local users to trigger invalid reads via malformed data. Versionize::deserialize allocates entries using one flexible-array length but retains a separately decoded, unchecked header length. A consuming application must deserialize data whose header length exceeds its entry count; later safe wrapper operations then read beyond the allocation.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
