Descriptions
Buffer overflow in system firmware for EDK II may allow unauthenticated user to potentially enable escalation of privilege and/or denial of service via network access.
Desbordamiento de búfer en el firmware del sistema para EDK II podría permitir que un usuario no autenticado escale privilegios y/o provoque una denegación de servicio mediante acceso de red.
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.
It was discovered that EDK II was not properly performing bounds checks in Tianocompress, which could lead to a buffer overflow. An authenticated user could use this issue to potentially escalate their privileges via local access. It was discovered that EDK II had an insufficient memory write check in the SMM service, which could lead to a page fault occurring. An authenticated user could use this issue to potentially escalate their privileges, disclose information and/or create a denial of service via local access.
