CVE-2003-0689

Estado: ModificadaAlta (7.5)—

La función getgrouplist en GNU libc (glibc) 2.2.4 y anteriores permite a los atacantes provocar una denegación de servicio (fallo de segmentación) y ejecutar código arbitrario cuando un usuario es miembro de un gran número de grupos, lo que puede causar un desbordamiento de búfer.
