  "summary": "Denial of service via deflate decompression bomb in github.com/russellhaering/gosaml2",
  "details": "A bug in SAML authentication library can result in Denial of Service attacks.\n\nAttackers can craft a `deflate`-compressed request which will consume significantly more memory during processing than the size of the original request. This may eventually lead to memory exhaustion and the process being killed.",
