Descripción
*** Pendiente de traducción *** libspdm is a sample implementation that follows the DMTF SPDM specifications. Prior to versions 2.3.3 and 3.0, following a successful CAPABILITIES response, a libspdm Requester stores the Responder&#39;s CTExponent into its context without validation. If the Requester sends a request message that requires a cryptography operation by the Responder, such as CHALLENGE, libspdm will calculate the timeout value using the Responder&#39;s unvalidated CTExponent.<br />
<br />
A patch is available in version 2.3.3. A workaround is also available. After completion of VCA, the Requester can check the value of the Responder&#39;s CTExponent. If it greater than or equal to 64, then the Requester can stop communication with the Responder.
