Summary
Improper uniqueness verification of signature threshold
Details

The tough library, prior to 0.7.1, does not properly verify the uniqueness of keys in the signatures provided to meet the threshold of cryptographic signatures. It allows someone with access to a valid signing key to create multiple valid signatures in order to circumvent TUF requiring a minimum threshold of unique keys before the metadata is considered valid.

AWS would like to thank Erick Tryzelaar of the Google Fuchsia Team for reporting this issue.

A fix is available in version 0.7.1.

CVE-2020-6174 is assigned to the same issue in the TUF reference implementation.
