SCA: security update for github.com/sigstore/gitsign (GHSA-8pmp-678w-c8xx)

low Tenable Self-Hosted Container Security Plugin ID 412790

Description

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

 - Gitsign is a keyless Sigstore to signing tool for Git commits with your a GitHub / OIDC identity. gitsign
 may select the wrong Rekor entry to use during online verification when multiple entries are returned by
 the log. gitsign uses Rekor's search API to fetch entries that apply to a signature being verified. The
 parameters used for the search are the public key and the payload. The search API returns entries that
 match either condition rather than both. When gitsign's credential cache is used, there can be multiple
 entries that use the same ephemeral keypair / signing certificate. As gitsign assumes both conditions are
 matched by Rekor, there is no additional validation that the entry's hash matches the payload being
 verified, meaning that the wrong entry can be used to successfully pass verification. Impact is minimal as
 while gitsign does not match the payload against the entry, it does ensure that the certificate matches.
 This would need to be exploited during the certificate validity window (10 minutes) by the key holder.
 (CVE-2024-51746)
