Exploitability
| CWE ID | Description |
|---|---|
| CWE-416 | The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer. |

What immediate steps should I take to mitigate this vulnerability?
Update Foxit PDF Reader to version 2025.2.1, 14.0.1, 13.2.1 or later on Windows and MacOS to fix the use-after-free vulnerability in annotation handling. Avoid opening PDF files from untrusted sources that may contain specially crafted JavaScript.
Can you explain this vulnerability to me?
This vulnerability is a use-after-free issue in the annotation handling of Foxit PDF Reader on Windows and MacOS versions before 2025.2.1, 14.0.1, and 13.2.1. It occurs when opening a PDF containing specially crafted JavaScript, which causes the program to access or dereference a pointer to memory that has already been freed. This can potentially allow a remote attacker to execute arbitrary code on the affected system.
How can this vulnerability impact me? :
The vulnerability can allow a remote attacker to execute arbitrary code on your system by tricking you into opening a malicious PDF file. This could lead to unauthorized control over your device, data theft, system compromise, or further malware installation.
