NVD Description

Note: Versions mentioned in the description apply only to the upstream kyverno-fips-1.15 package and not the kyverno-fips-1.15 package as distributed by Chainguard. See How to fix? for Chainguard relevant fixed versions and status.

go-tuf is a Go implementation of The Update Framework (TUF). Starting in version 2.0.0 and prior to version 2.3.1, a compromised or misconfigured TUF repository can have the configured value of signature thresholds set to 0, which effectively disables signature verification. This can lead to unauthorized modification to TUF metadata files is possible at rest, or during transit as no integrity checks are made. Version 2.3.1 fixes the issue. As a workaround, always make sure that the TUF metadata roles are configured with a threshold of at least 1.
