CVE-2025-34106

Estado: AplazadaAlta (8.4)—

A buffer overflow vulnerability exists in PDF Shaper versions 3.5 and 3.6 when converting a crafted PDF file to an image using the 'Convert PDF to Image' functionality. An attacker can exploit this vulnerability by tricking a user into opening a maliciously crafted PDF file, leading to arbitrary code execution under the context of the user. This vulnerability has been verified on Windows XP, 7, 8, and 10 platforms using the PDFTools.exe component.

CVSS

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).

🎯 Técnicas ATT&CK

Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.

Buffer overflow en PDF Shaper al abrir archivo crafted (UI:A); requiere interacción del usuario → T1203. Ejecuta código arbitrario → T1059.

Inferido por nuestro agente de análisis a partir de la descripción oficial, el vector CVSS y la CWE, y comprobado por un supervisor. Puede contener errores.
