SCA: security update for github.com/sigstore/sigstore-go (GHSA-cq38-jh5f-37mq)

low Tenable Cloud Security Plugin ID 414015

Description

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

 - sigstore-go, a Go library for Sigstore signing and verification, is susceptible to a denial of service
 attack in versions prior to 0.6.1 when a verifier is provided a maliciously crafted Sigstore Bundle
 containing large amounts of verifiable data, in the form of signed transparency log entries, RFC 3161
 timestamps, and attestation subjects. The verification of these data structures is computationally
 expensive. This can be used to consume excessive CPU resources, leading to a denial of service attack.
 TUF's security model labels this type of vulnerability an "Endless data attack," and can lead to
 verification failing to complete and disrupting services that rely on sigstore-go for verification. This
 vulnerability is addressed with sigstore-go 0.6.1, which adds hard limits to the number of verifiable data
 structures that can be processed in a bundle. Verification will fail if a bundle has data that exceeds
 these limits. The limits are 32 signed transparency log entries, 32 RFC 3161 timestamps, 1024 attestation
 subjects, and 32 digests per attestation subject. These limits are intended to be high enough to
 accommodate the vast majority of use cases, while preventing the verification of maliciously crafted
 bundles that contain large amounts of verifiable data. Users who are vulnerable but unable to quickly
 upgrade may consider adding manual bundle validation to enforce limits similar to those in the referenced
 patch prior to calling sigstore-go's verification functions. (CVE-2024-45395)
