CVE-2014-8121 (retired)

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.
Robin Hack discovered that the Name Service Switch (NSS)
implementation in the GNU C Library did not properly manage its file
descriptors. An attacker could use this to cause a denial of service
(infinite loop).
