USN-6796-1: TPM2 Software Stack vulnerabilities

Packages

tpm2-tss - TPM2 Software Stack library

Details

Fergus Dall discovered that TPM2 Software Stack did not properly handle
layer arrays. An attacker could possibly use this issue to cause
TPM2 Software Stack to crash, resulting in a denial of service, or
possibly execute arbitrary code.
(CVE-2023-22745)

Jurgen Repp and Andreas Fuchs discovered that TPM2 Software Stack did not
validate the quote data after deserialization. An attacker could generate
an arbitrary quote and cause TPM2 Software Stack to have unknown behavior.
(CVE-2024-29040)
