PDF Library vulnerabilities

There is an abnormal annotation within the PDF that is referenced by other objects. When the application parses the PDF, it fails to perform proper type checking, ultimately causing the application to crash.

When opening a PDF, the application fails to validate abnormal annotation relationships and field combinations related to hyperlinks, causing internal objects to enter an invalid state. During destruction, an invalid pointer write occurs, crashing the application.

Embedded JavaScript in a PDF file deleted pages, invalidating the object. The application attempted a write operation on invalid pop-up annotations, causing a crash.
