Synopsis
========

A vulnerability was found in R which could allow for remote code
execution.

Background
==========

R is a language and environment for statistical computing and graphics.

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

Package     Vulnerable    Unaffected
----------  ------------  ------------
dev-lang/R  < 4.0.4       >= 4.0.4

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

The native R package installation mechanisms do not sufficiently
validate installed source packages for path traversal.

Impact
======

Installation of a malicious R package could result in an arbitrary file
overwrite which could result in arbitrary code execution, as might be
seen with the overwrite of an authorized_keys file.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All R users should upgrade to the latest version:

  # emerge --sync
  # emerge --ask --oneshot --verbose ">=dev-lang/R-4.0.4"
