CVE-2010-4538

Estado: ModificadaAlta (9.3)—💥 Exploit

El desbordamiento de búfer en la función sect_enttec_dmx_da en el archivo epan/dissectors/packet-enttec.c en Wireshark versión 1.4.2, permite a los atacantes remotos causar una denegación de servicio (bloqueo de aplicación) o posiblemente ejecutar código arbitrario por medio de un paquete ENTTEC DMX especialmente diseñado con compresión Run Length Encoding (RLE).

CVSS

Versión: 2.0
Vector: AV:N/AC:M/Au:N/C:C/I:C/A:C
Puntuación base: 9.3

Probabilidad de explotación (EPSS)

Probabilidad de explotación en los próximos 30 días: 29%
Percentil entre todas las CVEs puntuadas: 98
Fecha de la puntuación: 9/10/2026

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.
