Severity: Medium
References: CVE-2014-0191 

Issue Overview:

It was discovered that libxml2, a library providing support to read, modify and write XML files, incorrectly performs entity substituton in the doctype prolog, even if the application using libxml2 disabled any entity substitution. A remote attacker could provide a specially-crafted XML file that, when processed, would lead to the exhaustion of CPU and memory resources or file descriptors.
