CVE-2021-43279

Estado: ModificadaAlta (7.8)—

An out-of-bounds write vulnerability exists in the U3D file reading procedure in Open Design Alliance PRC SDK before 2022.10. Crafted data in a U3D file can trigger a write past the end of an allocated buffer. An attacker can leverage this in conjunction with other vulnerabilities to execute arbitrary code in the context of the current process.

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).
