Estado: ModificadaAlta (7.8)—

Adobe After Effects version 18.4.1 (and earlier) is affected by a memory corruption vulnerability due to insecure handling of a malicious WAV file, potentially resulting in arbitrary code execution in the context of the current user. User interaction is required in that the victim must open a specially crafted file to exploit this vulnerability.

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).
