+title: HTTP response splitting in WEBrick (Additional fix)
+date: 2019-10-01
+description: |
+  If a program using WEBrick inserts untrusted input into the response header,
+  an attacker can exploit it to insert a newline character to split a header,
+  and inject malicious content to deceive clients.
+
+  This is the same issue as CVE-2017-17742. The previous fix was incomplete,
+  which addressed the CRLF vector, but did not address an isolated CR or an
+  isolated LF.
