NVD Description

Note: Versions mentioned in the description apply only to the upstream libjq-devel package and not the libjq-devel package as distributed by SLES. See How to fix? for SLES:16.0.0 relevant fixed versions and status.

jq is a command-line JSON processor. In 1.8.1 and earlier, jv_contains recurses into nested arrays/objects with no depth limit. With a sufficiently nested input structure (built programmatically with reduce, since the JSON parser caps at depth 10000), the C stack is exhausted.
