CVE-2025-65803Public exploitNetwork attack vector

Application crash via unchecked PSD row size

Published Dec 10, 2025 · Updated Dec 10, 2025

Integer overflow in FreeImage 3.18.0 and earlier allows context-dependent attackers to crash applications via a crafted PSD file. ReadImageData derives lineSize from an unvalidated PSD depth field and passes the oversized length to memcpy against a normally sized bitmap row. The target application must process the malicious file with uncompressed image data; the demonstrated consequence is a heap-buffer overflow and application crash.
