- Summary
- Incorrect threshold signature computation in TUF
- Details
-
Impact
Metadadata signature verification, as used in
tuf.client.updater, counted each of multiple signatures with identical authorized keyids separately towards the threshold. Therefore, an attacker with access to a valid signing key could create multiple valid signatures in order to meet the minimum threshold of keys before the metadata was considered valid.The tuf maintainers would like to thank Erik MacLean of Analog Devices, Inc. for reporting this issue.
Patches
A fix is available in version 0.12.2 or newer.
