Desbordamiento de búfer en BibTeX v0.99 permite a atacantes, dependiendo del contexto, provocar una denegación de servicio (corrupción de memoria y caída) a través de un fichero de bibliografía .bib grande.

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).

💥 Exploits públicos

Hay código de explotación o plantillas de detección públicos. No es lo mismo que explotación activa confirmada (KEV), pero aumenta el riesgo: parchee con prioridad.
