Subject: [PATCH] Fix nullptr deref with XPath logic ops
If the XPath stack is corrupted, for example by a misbehaving extension
function, the "and" and "or" XPath operators could dereference NULL
pointers. Check that the XPath stack isn't empty and optimize the
logic operators slightly.
Closes: https://gitlab.gnome.org/GNOME/libxml2/issues/5
Also see
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=901817
https://bugzilla.redhat.com/show_bug.cgi?id=1595985
This is CVE-2018-14404.
Thanks to Guy Inbar for the report.
