Summary
AMI AptioV firmware from AptioV_5.0 before AptioV_5.044 contains a buffer overflow in BIOS code. A local user with low privileges can trigger a classic buffer overflow (CWE-120) by copying input without checking its size. Successful exploitation can cause memory corruption and arbitrary code execution, with impact to confidentiality, integrity and availability.
