Descriptions

The nss_dns implementation of getnetbyname in GNU C Library (aka glibc) before 2.21, when the DNS backend in the Name Service Switch configuration is enabled, allows remote attackers to cause a denial of service (infinite loop) by sending a positive answer while a network name is being process.

La implementación nss_dns de getnetbyname en GNU C Library (también conocido como glibc) anterior a 2.21, cuando el backend DNS en la configuración Name Service Switch está habilitado, permite a atacantes remotos causar una denegación de servicio (bucle infinito) mediante el envió de una respuesta positiva mientras el nombre de una red está siendo procesada.

Many Cisco devices such as Cisco RV340, Cisco RV340W, Cisco RV345, Cisco RV345P, Cisco RV260, Cisco RV260P, Cisco RV260W, Cisco 160, and Cisco 160W suffer from having hard-coded credentials, known GNU glibc, known BusyBox, and IoT Inspector identified vulnerabilities.
