+date = "2017-05-06"
+description = """
+Affected versions of this crate use the `time` crate and the method
+`Duration::seconds` to parse the `Max-Age` duration cookie setting. This method
+will panic if the value is greater than 2^64/1000 and less than or equal to
+2^64, which can result in denial of service for a client or server.
+
+This flaw was corrected by explicitly checking for the `Max-Age` being in this
+integer range and clamping the value to the maximum duration value.
