DescriptionA heap buffer overflow flaw was found via the Tcg2MeasureGptTable() function in EDK2, arising from inadequate validation of the GPT Primary Header, presenting a minor risk to confidentiality and integrity. The primary consequence is likely a crash or denial of service. This issue may allow a local attacker to craft a GPT table, causing an integer overflow and consequent buffer overflow.A heap buffer overflow flaw was found via the Tcg2MeasureGptTable() function in EDK2, arising from inadequate validation of the GPT Primary Header, presenting a minor risk to confidentiality and integrity.
