NVD Description
Note: Versions mentioned in the description apply only to the upstream xmlrpc-c package and not the xmlrpc-c package as distributed by Ubuntu.
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.
