  "title": "Parser-reset denial of service in libexpat",
  "summary": "libexpat 2.7.2 through 2.9.0 is affected by a parser-reset memory-accounting flaw. An attacker who can supply a large XML document to a parser instance that is later reset and reused can make subsequent documents fail to parse until that parser is recreated.",
  "mitigation": "Do not reuse parser instances after they process untrusted large XML documents; recreate the parser before handling subsequent documents. Monitor for and apply an upstream libexpat update when one is released.",
