/** @file\r
The library instance provides security service of TPM measure boot. \r
\r
+ Caution: This file requires additional review when modified.\r
+ This library will have external input - PE/COFF image and GPT partition.\r
+ This external input must be validated carefully to avoid security issue like\r
+ buffer overflow, integer overflow.\r
+\r
+ DxeTpmMeasureBootLibImageRead() function will make sure the PE/COFF image content\r
+ read is within the image buffer.\r
+\r
+ TcgMeasurePeImage() function will accept untrusted PE/COFF image and validate its\r
+ data structure within this image buffer before use.\r
+\r
+ TcgMeasureGptTable() function will receive untrusted GPT partition table, and parse\r
+ partition data carefully.\r
