The register contents used for attestation or measurement reporting data to verify boot flow are modifiable by an adversary.
tpm2-tools is the source repository for the Trusted Platform Module (TPM2.0) tools. A malicious attacker can generate arbitrary quote data which is not detected by `tpm2 checkquote`. This issue was patched in version 5.7.
A flaw was found in the keylime attestation verifier, which fails to flag a device's submitted TPM quote as faulty when the quote's signature does not validate for some reason. Instead, it will only emit an error in the log without flagging the device as untrusted.
The tested version of Dominion Voting Systems ImageCast X’s on-screen application hash display feature, audit log export, and application export functionality rely on self-attestation mechanisms. An attacker could leverage this vulnerability to disguise malicious applications on a device.
