Insufficient memory write check in SMM service for EDK II may allow an authenticated user to potentially enable escalation of privilege, information disclosure and/or denial of service via local access.
(CVE-2018-12182)
Stack overflow in XHCI for EDK II may allow an unauthenticated user to potentially enable denial of service via local access. (CVE-2019-0161)
Buffer overflows were discovered in UDF-related codes under MdeModulePkg\Universal\Disk\PartitionDxe\Udf.c and MdeModulePkg\Universal\Disk\UdfDxe, which could be triggered with long file names or invalid formatted UDF media. (CVE-2019-0160)
Stack overflow in DxeCore for EDK II may allow an unauthenticated user to potentially enable escalation of privilege, information disclosure and/or denial of service via local access. (CVE-2018-12183)
Improper configuration in system firmware for EDK II may allow unauthenticated user to potentially enable escalation of privilege, information disclosure and/or denial of service via local access.
