NVD Description

Note: Versions mentioned in the description apply only to the upstream zot package and not the zot package as distributed by Minimos. See How to fix? for Minimos:latest relevant fixed versions and status.

sigstore-go is a Go library for Sigstore signing and verification. Prior to 1.2.0, a verifier configured with WithTransparencyLog(N>1) or WithSignedCertificateTimestamps(N>1) counts verified witnesses per entry or per validation path rather than per log authority, allowing a single compromised transparency log or CT log to satisfy multi-log threshold requirements and defeat the multi-log policy. This issue is fixed in version 1.2.0.
