NVD Description

Note: Versions mentioned in the description apply only to the upstream ruby2.5-doc package and not the ruby2.5-doc package as distributed by SLES.

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.
