Fedora 26: FEDORA-2018-a6b59d8f78 Critical: libxml2 Multiple Issues

This library allows to manipulate XML files. It includes support

to read, modify and write XML and HTML files. There is DTDs support

this includes parsing and validation even with complex DtDs, either

at parse time or later once the document has been modified. The output

can be a simple SAX stream or and in-memory DOM like representations.

In this case one can use the built-in XPath and XPointer implementation

to select sub nodes or ranges. A flexible Input/Output mechanism is

available, with existing HTTP and FTP modules and combined to an

URI library.

Update to 2.9.7 which hopefully fixes all security issues
