PDF-XChange Editor Heap-Based Buffer Overflow Vulnerability Leading to Remote Code Execution

A heap-based buffer overflow vulnerability has been identified in PDF-XChange Editor, specifically within the RTF file parsing component. This vulnerability allows remote attackers to execute arbitrary code on affected installations. The issue arises from inadequate validation of user-supplied data lengths before copying them into fixed-length heap-based buffers. Exploitation of this vulnerability requires user interaction, as the target must open a malicious file or visit a harmful webpage.

Impact
