HIGH7.5

In libexpat before 2

Published Sep 4, 2019

Modified 7 months ago

No fix available

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.
