Estado: AplazadaAlta (7.8)—

Heap buffer out-of-bounds read vulnerability in Avira Antivirus engine when scanning a malformed Windows MSI file may allow Local Execution of Code or Denial-of-Service of the antivirus engine process.

This issue affects Avira Antivirus on Windows, macOS, and Linux for engine builds before 8.3.70.56.

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.

Vector CVSS con AV:L y UI:R (apertura de archivo MSI malformado) indica ejecución en el cliente; heap buffer read permite RCE o DoS del motor antivirus.

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.
