Frequently Asked Questions
What malformed input condition leads to the out-of-bounds read?
A CRAT subtype whose header fits within the image but whose advertised length extends beyond the image boundary can trigger out-of-bounds reads during subtype parsing.
What check is required to prevent this condition?
Before parsing subtype contents, the parser must verify that the subtype header address plus its advertised length does not exceed the CRAT image boundary.
