  "summary": "CVE-2023-38039 is fixed in 34 products on 3 platforms, first by curl 8.2.1-1ubuntu3, released September 12, 2023. It is not reported as exploited. Patch Radar priority: High.",
  "title": "Hackerone: CVE-2023-38039 HTTP headers eat all memory",
  "description": "When curl retrieves an HTTP response, it stores the incoming headers so that they can be accessed later via the libcurl headers API.  However, curl did not have a limit in how many or how large headers it would accept in a response, allowing a malicious server to stream an endless series of headers and eventually cause curl to run out of heap memory.",
