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.
Weaknesses (CWE)
- CWE-125 — Out-of-bounds Read
- CWE-776 — Improper Restriction of Recursive Entity References in DTDs
