Overview

Affected versions of this package are vulnerable to Division by zero through the BPF interpreter when processing the div #k and mod #k ALU instructions without validating if the immediate value is zero. An attacker can cause a division-by-zero error by supplying a specially crafted filter program, resulting in a denial of service by crashing the process.
