CVE-2019-3690

Estado: ModificadaAlta (7.8)—

La herramienta chkstat en el paquete de permisos siguió los enlaces simbólicos antes del commit a9e1d26cd49ef9ee0c2060c859321128a6dd4230 (por favor también compruebe los hardenings adicionales después de esta corrección). Esto permitió a atacantes locales con control sobre una ruta que está atravesada por chkstat, escalar privilegios.

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).
