How to Fix CVE-2022-0317

To remediate this vulnerability, upgrade all affected Github.com/google/go attestation dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

github.com/google/go-attestation fixed: 0.4.0 
Upgrade github.com/google/go-attestation to 0.4.0
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

inspect dependencies for github.com/google/go-attestation

How to Check if You Are Affected

To determine whether your application is affected by CVE-2022-0317, inspect your project dependencies for Github.com/google/go attestation:

inspect dependencies for github.com/google/go-attestation

Analyze the terminal output to locate any version of Github.com/google/go attestation in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.4.0), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-20: Improper Input Validation, where the product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. In Github.com/google/go attestation, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### Impact An improper input validation vulnerability in go-attestation before 0.4.0 allows local users to provide a maliciously-formed Quote over no/some PCRs, causing `AKPublic.Verify` to succeed despite the inconsistency. Subsequent use of the same set of PCR values in `Eventlog.Verify` lacks the authentication performed by quote verification, meaning a local attacker could couple this vulnerability with a maliciously-crafted TCG log in `Eventlog.Verify` to spoof events in the TCG log, hence defeating remotely-attested measured-boot. ### Patches This issue is resolved in version 0.4.0. If your usage of this library verifies PCRs using multiple quotes, make sure to use the new method `AKPublic.VerifyAll()` instead of `AKPublic.Verify`.
