Debian DLA-2391-1 : ruby2.3 security update

Description

A potential HTTP request smuggling vulnerability in WEBrick was reported. WEBrick (bundled along with ruby2.3) was too tolerant against an invalid Transfer-Encoding header. This may lead to inconsistent interpretation between WEBrick and some HTTP proxy servers, which may allow the attacker to 'smuggle' a request. For Debian 9 stretch, this problem has been fixed in version 2.3.3-1+deb9u9. We recommend that you upgrade your ruby2.3 packages. For the detailed security status of ruby2.3 please refer to its security tracker page at: https://security-tracker.debian.org/tracker/ruby2.3 NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
