+This was reported in http://bugs.gnu.org/16872
+from the coreutils command: date -d 'TZ="""'
+
+The infinite loop for this case was present since the
+initial TZ="" parsing support in commit de95bdc2 29-10-2004.
+This was changed to a crash or heap corruption depending
+on the platform with commit 2e3e4195 18-01-2010.
+
+* lib/parse-datetime.y (parse_datetime): Break out of the
+TZ="" parsing loop once the second significant " is found.
+Also skip over any subsequent whitespace to be consistent
+with the non TZ= case.
+
+Fixes: CVE-2014-9471
+
+Upstream-Status: backport
