SCA: security update for github.com/sigstore/cosign (GHSA-8gw7-4j42-w388)

medium Tenable Cloud Security Plugin ID 412672

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Cosign is a project under the sigstore organization which aims to make signatures invisible
 infrastructure. In versions prior to 1.12.0 a number of vulnerabilities have been found in cosign verify-
 blob, where Cosign would successfully verify an artifact when verification should have failed. First a
 cosign bundle can be crafted to successfully verify a blob even if the embedded rekorBundle does not
 reference the given signature. Second, when providing identity flags, the email and issuer of a
 certificate is not checked when verifying a Rekor bundle, and the GitHub Actions identity is never
 checked. Third, providing an invalid Rekor bundle without the experimental flag results in a successful
 verification. And fourth an invalid transparency log entry will result in immediate success for
 verification. Details and examples of these issues can be seen in the GHSA-8gw7-4j42-w388 advisory linked.
 Users are advised to upgrade to 1.12.0. There are no known workarounds for these issues. (CVE-2022-36056)
