CVE-2025-8854

Estado: AnalizadaAlta (8.4)—

Stack-based buffer overflow in LoadOFF in bulletphysics bullet3 before 3.26 on all platforms allows remote attackers to execute arbitrary code via a crafted OFF file with an overlong initial token processed by the VHACD test utility or invoked indirectly through PyBullet's vhacd function.

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 archivo OFF procesado por utilidad VHACD (requiere interacción: abrir archivo preparado). Permite ejecución arbitraria de código en cliente/aplicación local.

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.
