title: Nokogiri affected by libxslt Use of Uninitialized Resource/
  Use After Free vulnerability
date: 2022-05-24
description: |
  In xsltCopyText in transform.c in libxslt 1.1.33, a pointer variable
  isn't reset under certain circumstances. If the relevant memory area
  happened to be freed and reused in a certain way, a bounds check could
  fail and memory outside a buffer could be written to, or uninitialized
  data could be disclosed.

  Nokogiri prior to version 1.10.5 contains a vulnerable version of
  libxslt. Nokogiri version 1.10.5 upgrades the dependency to
  libxslt 1.1.34, which contains a patch for this issue.
