CVE-2011-2910

Estado: ModificadaMedia (6.7)—

El demonio AX.25 (ax25d) en ax25-tools versiones anteriores a la versión 0.0.8-13 no comprueba el valor de retorno de una llamada setuid. La llamada setuid es responsable de eliminar los privilegios, pero si la llamada no funciona, el demonio continuará ejecutándose con privilegios de root que pueden permitir una posible escalada de 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).
