Descripción |
|
|
Se han descubierto dos vulnerabilidades en las versiones anteriores a la 2.6.11.10 del kernel de Linux. Las vulnerabilidades son descritas a continuación: - CAN-2005-1264: Vulnerabilidad en el manejo de ioctls en dispositivos de caracteres raw. La vulnerabilidad reside en el uso inadecuado de la función ioctl_by_bdev() que podría permitir sobrescribir memoria en espacio de kernel. - CAN-2005-1589: Vulnerabilidad en el manejo de ioctls en dispositivos de bloques pktcdvd. La vulnerabilidad reside en el uso inadecuado de la función ioctl_by_bdev() que podría permitir sobrescribir memoria en espacio de kernel. La explotación de estas vulnerabilidades podría permitir a un atacante local obtener privilegios de root. |
