Nokogiri vulnerable to libxslt protection mechanism bypass
A dependency of Nokogiri, libxslt through 1.1.33 allows bypass of a protection mechanism because callers of `xsltCheckRead` and `xsltCheckWrite` permit access even upon receiving a `-1` error code. `xsltCheckRead` can return `-1` for a crafted URL that is not actually invalid and is subsequently loaded.
