NVD Description

Note: Versions mentioned in the description apply only to the upstream glibc package and not the glibc package as distributed by Centos. See How to fix? for Centos:6 relevant fixed versions and status.

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.
