Debian DLA-2190-1 : ruby-json security update

high Nessus Plugin ID 136067
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

The remote Debian host is missing a security update.

Description

In ruby-json before 2.3.0, there is an unsafe object creation vulnerability. When parsing certain JSON documents, the json gem (including the one bundled with Ruby) can be coerced into creating arbitrary objects in the target system.

For Debian 8 'Jessie', this problem has been fixed in version 1.8.1-1+deb8u1.

We recommend that you upgrade your ruby-json 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 ruby-json package.
