Debian DLA-2192-1 : ruby2.1 security update

high Nessus Plugin ID 136202

Language:

Synopsis

The remote Debian host is missing a security update.

Description

The JSON gem through 2.2.0 for Ruby, as used in Ruby 2.1 has an unsafe object creation vulnerability. 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.

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.

Solution

Upgrade the affected packages.
