HIGH7.5EPSS 0.20%expat - security update
Published: 9/4/2019Modified: 4/28/2026
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.
