CVE-2020-11488

Estado: ModificadaMedia (6.7)—

NVIDIA DGX servers, all DGX-1 with BMC firmware versions prior to 3.38.30 and all DGX-2 with BMC firmware versions prior to 1.06.06, contains a vulnerability in the AMI BMC firmware in which software does not validate the RSA 1024 public key used to verify the firmware signature, which may lead to information disclosure or code execution.
