| Doc Text: |
A flaw was found in ipfixcol2. An unauthenticated remote attacker can cause a Denial of Service (DoS) by exhausting system memory. By sending crafted LZ4 compression headers with excessively large buffer size values over network connections, the application allocates excessive memory for each connection. This unbounded allocation can exhaust available system resources and render the collector service unavailable.
