EulerOS 2.0 SP2 : ruby (EulerOS-SA-2020-1686)

high Nessus Plugin ID 137528

Synopsis

The remote EulerOS host is missing a security update.

Description

According to the version of the ruby packages installed, the EulerOS installation on the remote host is affected by the following vulnerability :

- The JSON gem through 2.2.0 for Ruby, as used in Ruby 2.4 through 2.4.9, 2.5 through 2.5.7, and 2.6 through 2.6.5, 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.(CVE-2020-10663)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected ruby package.
