Descriptions
The get_contents function in nss_files/files-XXX.c in the Name Service Switch (NSS) in GNU C Library (aka glibc or libc6) before 2.20 might allow local users to cause a denial of service (heap corruption) or gain privileges via a long line in the NSS files database.
La función get_contents en nss_files/files-XXX.c en el Name Service Switch (NSS) en GNU C Library (también conocida como glibc o libc6) en versiones anteriores a 2.20 puede permitir a usuarios locales causar una denegación de servicio (corrupción de pila) o ganar privilegios a través de una larga fila en la base de datos de archivos NSS.
It was discovered that the nss_files backend for the Name Service Switch in glibc would return incorrect data to applications or corrupt the heap (depending on adjacent heap contents). A local attacker could potentially use this flaw to execute arbitrary code on the system.
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.
