This is quite similar to CVE-2013-0269, but does not rely on poor garbage-collection behavior within Ruby. Specifically, use of JSON parsing methods can lead to creation of a malicious object within the interpreter, with adverse effects that are application-dependent. For Debian 8 "Jessie", this problem has been fixed in version 2.1.5-2+deb8u10. We recommend that you upgrade your ruby2.1 packages.
