An improper input validation vulnerability in go-attestation before 0.3.3 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. We recommend upgrading to Version 0.4.0 or above.

GHSA-99cg-575x-774pGo-Attestation Improper Input Validation with attacker-controlled TPM Quote2022-02-01ghsa · osvUS
### 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`.
GO-2022-0294Improper input validation in github.com/google/go-attestation2022-07-15vendor · osvUS
A local attacker can defeat remotely-attested measured boot. Improper input validation in AKPublic.Verify can cause it to succeed when provided with a maliciously-formed Quote over no/some PCRs. Subsequent use of the same set of PCR values in Eventlog.Verify lacks the authentication performed by quote verification, meaning a local attacker can couple this vulnerability with a maliciously-formed TCG log in Eventlog.Verify to spoof events in the TCG log, defeating remotely-attested measured-boot.
