- 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.(CVE-2019-15903)
- XML External Entity vulnerability in libexpat 2.2.0 and earlier (Expat XML Parser Library) allows attackers to put the parser in an infinite loop using a malformed external entity definition from an external DTD.(CVE-2017-9233)
