NVD Description

Note: Versions mentioned in the description apply only to the upstream elasticsearch-8 package and not the elasticsearch-8 package as distributed by Minimos. See How to fix? for Minimos:latest relevant fixed versions and status.

Elasticsearch does not validate a size value taken from a user-supplied input before that value is used to reserve memory for an internal data structure. An authenticated user holding only read privileges can submit a single small crafted request to a product API endpoint that causes the node to attempt an excessively large allocation. The resulting memory exhaustion raises a fatal error that terminates the Elasticsearch node process, causing a denial of service for the affected node and degrading cluster health. The defect is not volumetric, so a single request is sufficient regardless of the heap size configured on the target node.
