What to do
AI-suggested
European organizations should implement a multi-layered mitigation strategy. If you cannot patch yet, disable JavaScript execution within Foxit PDF and Editor applications to reduce the attack surface, as the vulnerability exploits JavaScript in PDFs. Enhance email and endpoint security by deploying advanced malware detection solutions capable of scanning and sandboxing PDF attachments to identify malicious content. Conduct user awareness training focused on the risks of opening unsolicited or unexpected PDF files, emphasizing caution with email attachments and downloads. Implement network segmentation and least privilege principles to limit the impact of potential compromises. Employ application whitelisting to restrict execution of unauthorized code. Consider deploying Data Loss Prevention (DLP) tools to monitor sensitive data flows. Regularly audit and update security policies related to document handling. Finally, maintain robust incident response plans to quickly detect and respond to exploitation attempts.
Description
An issue was discovered in Foxit PDF and Editor for Windows and macOS before 13.2 and 2025 before 2025.2. They 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. This can result in memory corruption and may allow an attacker to execute arbitrary code by persuading a user to open a malicious file.
