Vulnerability Data
An issue was discovered in Foxit PDF and Editor for Windows before 13.2 and 2025 before 2025.2. When pages in a PDF are deleted via JavaScript, the application may fail to properly update internal states. Subsequent annotation management operations assume…

these states are valid, causing dereference of invalid or released memory. This can lead to memory corruption, application crashes, and potentially allow an attacker to execute arbitrary code.

Mitigating Controls (NIST 800-53 r5) AI
Directly enforces memory protections that block exploitation of invalid or released memory dereferences caused by improper state updates after JavaScript page deletions.
Requires validation of PDF/JavaScript inputs and resulting internal state changes to avoid creation of inconsistent states that trigger the NULL dereference.
Ensures graceful error handling for invalid memory references instead of allowing corruption or arbitrary code execution during subsequent annotation operations.

Security testing can detect NULL dereference defects before release.
Secure SDLC mandates defensive coding practices that can prevent NULL dereferences.
Application security requirements can specify input validation and pointer-safety rules.
Secure architecture principles encourage defensive design that avoids unsafe pointer use.
Secure coding standards directly require NULL-pointer checks and safe dereference patterns.
