Arbitrary Code Execution

Description

libxml2 is vulnerable to arbitrary code execution. The vulnerability exists as lparser.c in libxml2 before 2.9.5 mishandles parameter-entity references because the NEXTL macro calls the xmlParserHandlePEReference function in the case of a '%' character in a DTD name.

libxml2:3.4 2.9.4-r3
