Descriptions
In klibc 1.5.20 and 1.5.21, the DHCP options written by ipconfig to /tmp/net-$DEVICE.conf are not properly escaped. This may allow a remote attacker to send a specially crafted DHCP reply which could execute arbitrary code with the privileges of any process which sources DHCP options.
En klibc versiones 1.5.20 y 1.5.21, las opciones de DHCP escritas por ipconfig en el archivo /tmp/net-$DEVICE.conf no se escapan apropiadamente. Esto puede permitir a un atacante remoto enviar una respuesta DHCP especialmente diseñada que podría ejecutar código arbitrario con los privilegios de cualquier proceso que genere opciones DHCP.
