WS-2022-0159
Good to know:
Date: June 17, 2022
In tss-esapi in Rust When Context::start_auth_session was called with a nonce argument value of Some(...), the nonce pointer passed down through FFI to Esys_StartAuthSession would be a dangling pointer, left over from a defunct instance of TPM2B_NONCE. This issue may affect memory safety. Versions 6.1.2 and 7.1.0 contain a patch for this issue .
