CVE-2012-1568

Estado: ModificadaBaja (1.9)—

La característica en algunos parches para el kernel de Red Hat en las versiones Enterprise Linux (RHEL) 5 y 6 y fedora 15 y 16, no maneja adecuadamente el uso de varias librerías compartidas por los archivos ejecutables de 32 bit, lo que facilita a atacantes dependientes del contexto, evitar los mecanismos de protección aprovechando una base de direcciones predecibles para una de estas librerías.

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).
