    CVE-2023-22745

    Summary: Updated tpm2-tss packages fix security vulnerability

    Details: Tss2_RC_SetHandler and Tss2_RC_Decode both index into layer_handler with an 8 bit layer number, but the array only has TPM2_ERROR_TSS2_RC_LAYER_COUNT entries, so trying to add a handler for higher-numbered layers or decode a response code with such a layer number reads/writes past the end of the buffer. (CVE-2023-22745)
