3.2.2

[3.2.2] - 2023-01-31

Fixed:

• A buffer overflow in tss2-rc as CVE-2023-22745.
• The drv layer in tss2-rc should have been the policy layer.
• Spec deviation in Fapi_GetDescription caused description to be NULL when it should be empty string.
  This is API breaking but considered a bug since it deviated from the FAPI spec.
• FAPI: undefined reference to curl_url_strerror when using curl less than 7.80.0.

• Store VERSION into the release tarball.
• When using DESTDIR for make einstall, do not invoke systemd-sysusers and systemd-tmpfiles.
• esys_iutil: fix possible NPD.

• esys: fix allow usage of HMAC sessions for Esys_TR_FromTPMPublic.
• fapi: fix usage of policy_nv with a TPM nv index.
