Stack overflow vulnerability in Aspire E5-475G 's BIOS firmware, in the FpGui module, a second call to GetVariable services allows local attackers to execute arbitrary code in the UEFI DXE phase and gain escalated privileges.

A potential Time-of-Check to Time-of-Use (TOCTOU) vulnerability has been identified in certain HP PC products using AMI UEFI Firmware (system BIOS) which might allow arbitrary code execution, denial of service, and information disclosure. AMI has released updates to mitigate the potential vulnerability.
