-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

-This is CVE-2018-14404.

-Thanks to Guy Inbar for the report.
