title: Moderate severity vulnerability that affects nokogiri
date: 2018-04-13
description: |
  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.
