  "summary": "Updated perl-Starman packages fix security vulnerability",
  "details": "Starman versions before 0.4018 for Perl allow HTTP Request Smuggling\nvia Improper Header Precedence.\nStarman incorrectly prioritizes \"Content-Length\" over\n\"Transfer-Encoding: chunked\" when both headers are present in an HTTP\nrequest. Per RFC 7230 3.3.3, Transfer-Encoding must take precedence.\nAn attacker could exploit this to smuggle malicious HTTP requests via a\nfront-end reverse proxy.\n",
