security advisory security issue critical debian ruby http request smuggling webrick

Summary

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:
