DXE capsule library.
|
|
|
|
Caution: This module requires additional review when modified.
|
|
This module will have external input - capsule image.
|
|
This external input must be validated carefully to avoid security issue like
|
|
buffer overflow, integer overflow.
|
|
|
|
SupportCapsuleImage(), ProcessCapsuleImage(), IsValidCapsuleHeader(),
|
|
ValidateFmpCapsule(), DisplayCapsuleImage(), ConvertBmpToGopBlt() will
|
|
receive untrusted input and do basic validation.
