MdePkg: Fix overflow issue in BasePeCoffLib
|
||||
|
||||
The RelocDir->Size is a UINT32 value, and RelocDir->VirtualAddress is
|
||||
also a UINT32 value. The current code does not check for overflow when
|
||||
adding RelocDir->Size to RelocDir->VirtualAddress. This patch adds a
|
||||
check to ensure that the addition does not overflow.
