[Security Fix]
- expatには、XML名にたくさんのコロン(":")が
含まれたXMLが入力されると、大量の(サービス拒否
攻撃をする為に十分な量の)CPUとメモリリソースを
消費する脆弱性があります。(CVE-2018-20843)
- expatには、巧妙に細工されたXMLが入力されると、
パーサーがDTDの構文解析から、より早期にドキュメント
の構文解析に切り替えてしまい、XML_GetCurrentLineNumber
(又はXML_GetCurrentColumnNumber)への連続
呼び出しが発生することでヒープ領域のバッファ・
オーバーフローを引き起こす脆弱性があります。

CVE:
CVE-2018-20843
In libexpat in Expat before 2.2.7, XML input including XML names that contain a large number of colons could make the XML parser consume a high amount of RAM and CPU resources while processing (enough to be usable for denial-of-service attacks).

CVE-2019-15903
In libexpat before 2.2.8, crafted XML input could fool the parser into changing from DTD parsing to document parsing too early; a consecutive call to XML_GetCurrentLineNumber (or XML_GetCurrentColumnNumber) then resulted in a heap-based buffer over-read.
