Description
A flaw was found in jq, a command line JSON processor. Processing a crafted JSON document, specifically when a large array is used as a path argument to the jv_setpath, jv_getpath and delpaths_sorted functions can lead to an uncontrolled recursion and exhausts the call stack, causing an application crash and resulting in a denial of service.
Statement
To exploit this issue, an attacker needs to supply a crafted JSON input to be processed by jq with the setpath, getpath or delpaths builtins. This allows the attacker to cause an application crash with no other security impact. Due to these reasons, this flaw has been rated with a moderate severity.
