When the application opens a PDF file and JavaScript writes annotation attributes, there is a lack of sufficient object type and argument checks. As a result, due to the damage to the internal structure of the annotations, it causes the application to crash during subsequent release.
After the application opened the PDF file, the script first reset the annotation status, then triggered the reset form event by additional action. During the re-entry process, the application access invalid objects and crashed.
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.
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.
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.
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.
A heap buffer overflow in BitmapScaleBitmaps in libXfont2 before 2.0.8 due to an overflowing 32bit size could be used by attackers able to access the X Server to execute code within the X server cont
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.
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.
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.
