CWE-88  (opens in a new tab)

How to fix?

Upgrade Centos:7 rubygem-psych to version 0:2.0.0-35.el7_6 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream rubygem-psych package and not the rubygem-psych package as distributed by Centos. See How to fix? for Centos:7 relevant fixed versions and status.

An issue was discovered in RubyGems 2.6 and later through 3.0.2. Since Gem::CommandManager#run calls alert_error without escaping, escape sequence injection is possible. (There are many ways to cause an error.)
