Threat Intelligence
The probability is the direct output of the EPSS model, and conveys an overall sense of the threat of exploitation in the wild. The percentile measures the EPSS probability relative to all known EPSS scores. Note: This data is updated daily, relying on the latest available EPSS model version.

Upgrade mariadb to version 3.2.5, 3.3.4, 3.4.7, 3.5.4 or higher.
Overview
Affected versions of this package are vulnerable to Use of Uninitialized Resource via the GeoJSON Polygon and MultiPolygon encoding path in lib/cmd/encoder/binary-encoder.js when a ring element within the coordinates array is not a real array. The encoder sizes the output buffer using Buffer.allocUnsafe based on each ring's length property, then writes coordinate data only when the ring passes an Array.isArray check. When a non-array ring is supplied, the writing loop is skipped while the allocated bytes remain uninitialized, causing process heap memory to be transmitted to the database server in the binary protocol packet. An attacker who can supply GeoJSON Polygon or MultiPolygon query parameters can leak arbitrary Node.js process memory to the server.
