CWEhttps://cwe.mitre.org/data/definitions/134.html

Ruby before 2.4.2, 2.3.5, and 2.2.8 is vulnerable to a malicious format string which contains a precious specifier (*) with a huge minus value. Such situation can lead to a buffer overrun, resulting in a heap memory corruption or an information disclosure from the heap.

Weakness

The product uses a function that accepts a format string as an argument, but the format string originates from an external source.
