| Doc Text: |
A flaw was found in jq, a command line JSON processor. The `jv_object_merge_recursive` function, reachable via the `*` operator when both operands are objects, does not have a depth limit when processing nested objects. This missing depth limit allows an attacker who can supply a sufficiently nested input structure to exhaust the stack memory, causing an application crash and resulting in a denial of service.
