TCG TPM2 Software Stack is a library to interface with trusted platform modules.
TCG TPM2 Software Stack did not appropriately apply FAPI policies to protect data encrypted with the trusted platform module.
Data encrypted using TCG TPM2 Software Stack (tpm2-tss) may not be protected from an attacker.
There is no known workaround at this time.
All tpm2-tss users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=app-crypt/tpm2-tss-2.4.3"
