    CVE-2019-15903

    Published: 4 Sept 2019Last Modified: 7 Aug 2026

    Summary:

    Details: 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.
