Calendar Grey February 17, 2023
Dist Fedora Esm H88
Patch implemented for address overflow vulnerability in tpm2-tools, rectifying API flaws within Fedora 36 concerning CVE-2023-22745.
Fixed: * A buffer overflow in tss2-rc as CVE-2023-22745

Summary

tpm2-tools is a batch of tools for tpm2.0. It is based on tpm2-tss.

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.
