CVE-2019-15903

HIGH

libexpat < 2.2.8 - XML External Entity Injection via DTD Parsing

Title source: llm

Description

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.
