Description GLSAMaker/CVETool Bot gentoo-dev 2015-06-21 00:23:41 UTC
CVE-2014-8121 (
  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 while the database is iterated over
  the database, which triggers the file pointer to be reset.
Comment 1 SpanKY gentoo-dev 2015-07-21 03:13:16 UTC
this is fixed in glibc-2.22, but i don't plan on trying to backport it as it touches a few more files/logic than i'm comfortable with backporting
Comment 2 SpanKY gentoo-dev 2016-02-16 19:05:53 UTC
i've included this in glibc-2.21-r2 now; stabilization is via bug 574880
