- Private changed from Yes to No
This issue involves an evil client and an evil server which repeat the same pattern, expensive in terms of CPU
The evil server sends a HTTP response with two layers of lzma compression
Workaround is to set lzma-enabled: false in suricata.yaml (lzma-enabled is commented by default)
Another workaround is to set response-body-decompress-layer-limit: 1 in suricata.yaml (default value is 2)
