An attacker could send a\nmalicious request with an abnormally large `Content-Length`, which could lead\nto a panic if memory allocation failed for that request.\n\nIn version 0.4.2, `conduit-hyper` sets an internal limit of 128 MiB per\nrequest, otherwise returning status 400 (\"Bad Request\").\n\n## Affected packages\n\n- `conduit-hyper >= 0.2.0-alpha.3, < 0.4.2`\n\n## Remediation\n\nUpgrade to a patched release:\n\n- `conduit-hyper 0.4.2`","depth":"twilight","depthScore":41,"depthScoreParts":{"impact":41.3,"likelihood":0.1,"exploitation":0,"ransomware":0},"changes":[]}
