More information:

Several security vulnerabilities were found in Ruby that also affected Debian's JRuby package, a pure-Java implementation of Ruby. Attackers were able to call arbitrary Ruby methods, cause a denial-of-service or inject input into HTTP response headers when using the WEBrick module.

For Debian 8 Jessie, these problems have been fixed in version 1.5.6-9+deb8u2.

We recommend that you upgrade your jruby packages.
