Security Vulnerabilities
An abnormal image object causes the renderer to enter the wrong processing branch. When converting the scan lines, an invalid image buffer pointer is used, resulting in the application crashing.

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.

The application opens a PDF containing an abnormal color space whose attributes reference a valid but semantically malformed function. The function's output is not validated; when subsequently read, it produces an illegal pointer that accesses an out-of-bounds region, crashing the application.

When the application opens a PDF and executes JavaScript, it performs abnormal operations on the list box field, and this operation is repeated after the form is reset. During this process, the application failed to adequately verify the validity of the form objects and their internal dictionary pointers, resulting in accessing internal members of invalid or improperly initialized fields. This led to an illegal pointer read, ultimately causing the application to crash.

During the PRC parsing stage, there is a lack of boundary verification for the PRC entity index, which leads to an out-of-bounds read of the entity array. As a result, the application crashes.

The application opens the PDF, and JavaScript performs operations on the page and the document, causing the page-related objects within the application to lose synchronization; however, the renderer still trusts the outdated page count, and eventually the application crashes due to out-of-bounds access.

The application opens the PDF, and JavaScript modifies the form. However, the related objects on the page lack complete lifecycle management and null value validation; when the page state changes, the application continuously dereferences invalid objects, eventually leading to a crash.

During the process of page opening and form formatting, a JavaScript reentrancy results in an inconsistent document status. Subsequently, with outdated page information, the application attempts to access invalid addresses, causing the application to crash.

After JavaScript resetting the form, the synchronization process lacks re-entry protection and object lifecycle verification, resulting in the failure of the control pointer during the traversal process. After the pointer fails, it still continues to dereference, causing the application to crash.

When the application opens a PDF, traverses and builds the annotation elements related to hyperlinks, it fails to validate the abnormal annotation relationships and field combinations. This results in the internal objects entering an invalid state. Eventually, during the destruction phase, an invalid pointer write occurred, causing the application to crash.
