CVE-2022-35929
Description
A flaw was found in the cosign package. The cosign verify-attestation used with the --type flag will report a false positive verification when there is at least one attestation with a valid signature and when there are no attestations of the type being verified (for example, —type defaults to "custom"). This issue can happen when signing with a standard keypair and keyless signing with Fulcio.
Statement
The cosign package is a transitive dependency and is not used directly in the Red Hat Advanced Cluster Security product. Hence, it is categorized as a Moderate impact.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
The following CVSS metrics and score provided are preliminary and subject to review.
