NVD Description

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

In Ruby before 2.2.10, 2.3.x before 2.3.7, 2.4.x before 2.4.4, 2.5.x before 2.5.1, and 2.6.0-preview1, an attacker controlling the unpacking format (similar to format string vulnerabilities) can trigger a buffer under-read in the String#unpack method, resulting in a massive and controlled information disclosure.
