A local privilege escalation vulnerability exists in the updater of Foxit PDF Editor/Reader due to unsafe loading of dynamic-link libraries from a user-writable directory during high-privilege operations. A local attacker could exploit this issue to execute code with elevated privileges.

A vulnerability in Foxit PDF Editor/Reader’s update mechanism allows an update package to be replaced between download and high-privilege extraction due to insufficient file locking and integrity validation. This could enable local attackers to execute arbitrary code with elevated privileges.

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.

A vulnerability in Foxit PDF Editor/Reader’s update mechanism allows man-in-the-middle attackers to bypass certificate validation and package integrity checks, potentially enabling arbitrary code execution with system privileges.

When dealing with abnormally constructed objects, there is a lack of argument validation; JavaScript triggers signature verification, but the signature plugin does not perform validation when copying the abnormal string, causing the application to crash.

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 file, during the process of JavaScript deleting pages and removing attachment annotations, it will cause the attachment panel to continue accessing invalid pointers, eventually leading to the application crashing.

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.

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.

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.

When the application opens a PDF and JavaScript resets the form fields, the script re-enters the interface. The underlying native object is damaged, but the application does not perform validation. The function call on the damaged object leads to the application crashing.

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.

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 application re-enters the document structure via field processing and deletes the current page, and then continues using the field objects obtained before deletion, triggering an illegal read and crashing.

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 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.

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 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.

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.

The application opened a PDF file containing an abnormal Unity 3D object. During parsing, the application incorrectly resolved a portion of the abnormal object as a pointer and used it as a valid address, ultimately causing the application to crash.

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.

Foxit PDF Editor/Reader's FileOpen plugin did not adequately validate certain encryption metadata in specially crafted PDF files. This could leave an internal pointer in an invalid state, resulting in chained read and write access violations and potentially enabling arbitrary code execution.

When opening a specially crafted PDF, Foxit PDF Editor/Reader executes scripts that modify annotation rich-text attributes containing malformed font data. During subsequent annotation appearance reconstruction, it accesses an object after it has been released, resulting in a use-after-free condition and an application crash.

A use-after-free vulnerability exists in Foxit PDF Editor/Reader’s handling of malformed PDF form fields. Improper validation during field-name traversal may cause the application to access a released object, resulting in an application crash.

A use-after-free vulnerability exists in Foxit PDF Editor/Reader’s handling of PDF annotations. Reentrant annotation deletion triggered by embedded JavaScript can cause the application to access an annotation object after it has been released, resulting in a use-after-free condition and application crash.

A use-after-free vulnerability exists in Foxit PDF Editor/Reader’s JavaScript handling of PDF annotations. Reentrant page-event processing during annotation enumeration may release the associated page object, which is subsequently accessed, resulting in an application crash.

A path traversal vulnerability exists in Foxit PDF Editor/Reader's handling of embedded PDF resources. Insufficient validation of resource file paths may allow files to be written outside their intended locations, potentially enabling arbitrary code execution.
