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.
Affected configurations
• suse suse linux enterprise desktop 11
• suse suse linux enterprise server 11.0
• gnu glibc (<= 2.21)
• canonical ubuntu linux 12.04
• canonical ubuntu linux 14.04
