title: Nokogiri gem, via libxslt, is affected by improper access control vulnerability
description: |
  Nokogiri v1.10.3 has been released.

  This is a security release. It addresses a CVE in upstream libxslt rated as
  "Priority: medium" by Canonical, and "NVD Severity: high" by Debian. More
  details are available below.

  If you're using your distro's system libraries, rather than Nokogiri's
  vendored libraries, there's no security need to upgrade at this time, though
  you may want to check with your distro whether they've patched this
  (Canonical has patched Ubuntu packages). Note that this patch is not yet (as
  of 2019-04-22) in an upstream release of libxslt.

  Full details about the security update are available in Github Issue
  [#1892] https://github.com/sparklemotion/nokogiri/issues/1892.

  CVE-2019-11068

  Permalinks are:
  - Canonical: https://people.canonical.com/~ubuntu-security/cve/CVE-2019-11068
  - Debian: https://security-tracker.debian.org/tracker/CVE-2019-11068

  Description:

  > 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.

  Canonical rates this as "Priority: Medium".

  Debian rates this as "NVD Severity: High (attack range: remote)".
