The input file does not need to be strictly in a structurally valid PDF format. Instead, after reviewing the content, the original document disguised as a PDF will be sent to the parser. Malicious documents will construct malicious external entities that, through the protocol, point to local paths, thereby allowing access to any local files within the user's permission range.

The application opens a PDF, but the cloud-like appearance of the construction process lacks proper setting of an upper limit and consistency checks. Out-of-bounds access to the underlying array is exposed, ultimately leading to a crash of the application.
