Synopsis
========

Multiple vulnerabilities were found in RubyGems, the worst of which
allows execution of arbitrary code.

Background
==========

RubyGems is a sophisticated package manager for Ruby.

Affected packages
=================

    -------------------------------------------------------------------
     Package              /     Vulnerable     /            Unaffected

Description
===========

Multiple vulnerabilities have been discovered in RubyGems. Please
review the referenced CVE identifiers for details.

Impact
======

A remote attacker, by enticing a user to install a specially crafted
gem, could possibly execute arbitrary code with the privileges of the
process or cause a Denial of Service condition.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All RubyGems users should upgrade to the latest version:

  # emerge --sync
  # emerge --ask --oneshot --verbose ">=dev-ruby/rubygems-2.6.13"
