Description

A flaw was found in jq, a tool used for processing JSON data from the command line. A remote attacker can exploit a vulnerability by providing a specially crafted large number as input. This can cause an internal calculation error, leading to a memory overflow where the attacker can write their own data into the system's memory, potentially resulting in the application crashing (Denial of Service).
