Description

A flaw was found in jq, a command line JSON processor. The `jv_contains` function does not have a depth limit when processing nested arrays or 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.
