This vulnerability has been modified since it was last analyzed by the NVD. It is awaiting reanalysis which may result in further changes to the information provided.
Description
DB_LOOKUP in nss_files/files-XXX.c in the Name Service Switch (NSS) in GNU C Library (aka glibc or libc6) 2.21 and earlier does not properly check if a file is open, which allows remote attackers to cause a denial of service (infinite loop) by performing a look-up on a database while iterating over it, which triggers the file pointer to be reset.

It was found that the files back end of Name Service Switch (NSS) did not isolate iteration over an entire database from key-based look-up API calls. An application performing look-ups on a database while iterating over it could enter an infinite loop, leading to a denial of service.

DB_LOOKUP en nss_files/files-XXX.c en Name Service Switch (NSS) en GNU C Library (también conocida como glibc o libc6) 2.21 y versiones anteriores no comprueba correctamente si un archivo está abierto, lo que permite a atacantes remotos causar una denegación de servicio (bucle infinito) realizando una búsqueda en una base de datos mientras itera sobre ella, lo que desencadena que el puntero al archivo sea reestablecido.
