A vulnerability was determined in jqlang jq up to 1.6. Impacted is the function run_jq_tests of the file jq_test.c of the component JSON Parser. Executing manipulation can lead to reachable assertion. The attack requires local access. The exploit has been publicly disclosed and may be utilized. Other versions might be affected as well.
The product contains an assert() or similar statement that can be triggered by an attacker, which leads to an application exit or other behavior that is more severe than necessary.
While assertion is good for catching logic errors and reducing the chances of reaching more serious vulnerability conditions, it can still lead to a denial of service. For example, if a server handles multiple simultaneous connections, and an assert() occurs in one single connection that causes all other connections to be dropped, this is a reachable assertion that leads to a denial of service.
