CVE-2025-6660 is a heap-based buffer overflow vulnerability in PDF-XChange Editor's GIF file parsing engine that enables remote code execution with high severity (CVSS 7.8). The vulnerability affects users who open malicious GIF files or visit compromised web pages hosting malicious GIFs, requiring user interaction for exploitation. The flaw stems from inadequate validation of user-supplied data lengths before copying to fixed-length buffers, allowing attackers to overwrite heap memory and execute arbitrary code in the application's context.
CVE-2025-6659 is an out-of-bounds write vulnerability in PDF-XChange Editor's PRC file parser that allows remote code execution with high integrity and confidentiality impact (CVSS 7.8). The vulnerability affects PDF-XChange Editor users who open malicious PRC files or visit compromised websites, requiring user interaction but no special privileges. While the vulnerability demonstrates significant local exploitation potential, real-world risk depends on KEV/CISA status, EPSS probability data, and proof-of-concept availability, which would indicate active threat actor interest.
