4 | Caution: This module requires additional review when modified.\r | |
5 | This module will have external input - capsule image.\r | |
6 | This external input must be validated carefully to avoid security issue like\r | |
7 | buffer overflow, integer overflow.\r | |
8 | \r | |
9 | ProcessCapsules(), ProcessTheseCapsules() will receive untrusted\r | |
10 | input and do basic validation.\r | |
