Nokogiri (鋸) is an HTML, XML, SAX, and Reader parser. Among
Nokogiri's many features is the ability to search documents via XPath
or CSS3 selectors.
XML is like violence - if it doesn’t solve your problems, you are not
using enough of it.
The xz_head function in xzlib.c in libxml2 before 2.9.6 allows remote attackers to cause a denial of service (memory consumption) via a crafted LZMA file, because the decoder functionality does not restrict memory usage to what is required for a legitimate file.
