Foxit PDF and Editor vulnerabilities

An issue was discovered in Foxit PDF and Editor for Windows and macOS 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.

Foxit PDF and Editor for Windows and macOS before 13.2 and 2025 before 2025.2 allow potential arbitrary code execution when processing crafted PDF files. The vulnerability stems from insufficient handling of memory allocation failures after assigning an extremely large value to a form field's charLimit property via JavaScript, which can cause memory corruption. An attacker can exploit this by persuading a user to open a malicious file.

An issue was discovered in Foxit PDF and Editor for Windows and macOS before 13.2 and 2025 before 2025.2. A crafted PDF can contain JavaScript that attaches an OnBlur action on a form field that destroys an annotation; during user right-click interaction, the program's internal focus change handling prematurely releases the annotation object, resulting in a use-after-free vulnerability that may cause memory corruption or application crashes.

An issue was discovered in Foxit PDF and Editor for Windows before 13.2 and 2025 before 2025.2. A crafted PDF containing JavaScript that calls closeDoc() while internal objects are still in use can cause premature release of these objects; this use-after-free vulnerability may lead to memory corruption, potentially resulting in information disclosure when the PDF is opened.
