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.

Affected configurations

• libexpat project libexpat (< 2.2.8) • python python (>= 2.7.0 < 2.7.17) • python python (>= 3.5.0 < 3.5.8) • python python (>= 3.6.0 < 3.6.10) • python python (>= 3.7.0 < 3.7.5)
