Kerentanan Memory Allocation with Excessive Size Value pada elasticsearch. Skor CVSS 3.1 6.5 (Medium) menurut elastic.co.

Deskripsi (NVD)

A flaw in Elasticsearch allows a low-privileged authenticated user to submit a single small request containing a forged opaque identifier. Elasticsearch decodes and deserializes the identifier before confirming that it was legitimately issued by the cluster, and a size value carried inside the identifier drives an allocation that is neither capped nor accounted for by the available memory-usage controls. The resulting out-of-memory condition is fatal and terminates the affected node process, resulting in a denial of service.
