    Summary: Nokogiri does not forbid namespace nodes in XPointer ranges

    Details: xpointer.c in libxml2 before 2.9.5 (as used in nokogiri before 1.7.1 amongst other products) does not forbid namespace nodes in XPointer ranges, which allows remote attackers to execute arbitrary code or cause a denial of service (use-after-free and memory corruption) via a crafted XML document.
