Описание
notation-go has excessive memory allocation on verification
Impact
notation-go users will find their application using excessive memory when verifying signatures and the application will be finally killed, and thus availability is impacted.
Patches
The problem has been patched in the release v1.0.0-rc.3. Users should upgrade their notation-go packages to v1.0.0-rc.3 or above.
Workarounds
Users can review their own trust policy file and check if the identity string contains =#. Meanwhile, users should only put trusted certificates in their trust stores referenced by their own trust policy files, and make sure the authenticity validation is set to enforce
