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.
