When the application opens a PDF file and JavaScript deletes the PDF fields, the subsequent logic still uses the old field pointers, resulting in invalid pointer references and causing the application to crash.
The user-controllable executable files will be directly executed by high-privilege processes, allowing low-privilege users to have the opportunity to elevate their privileges to NT AUTHORITY\SYSTEM.
After the application opened the PDF, JavaScript deleted the form field object. Subsequently, it attempted to access the invalid object, which caused the application to crash.
When the application opens a PDF and JavaScript modifies the properties of form fields, it causes the state of the underlying objects referenced by the program to become invalid. Eventually, it reads an illegal memory address, which leads to the crash of the application.
When the application opens a PDF file, JavaScript uses the damaged field tree to trigger field traversal, resulting in the program holding an invalid form object when accessing the field property path. Eventually, the application crashes due to reading an invalid pointer.
Embedding JavaScript within a PDF file will cause the page to be deleted. Subsequent scripts will continue to access the relevant properties of the document view, eventually leading to the crash of the application.
The application opens the PDF file. JavaScript then rewrites the document to modify the page structure, resulting in the invalidation of the page objects. However, the thumbnails still use the invalid page objects, ultimately causing the application to crash.
The embedded JavaScript in the PDF deleted the pages, making the object invalid. The application attempted to perform a write operation on the invalid pop-up annotations, resulting in the program crashing.
