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
---------- ------------ ------------

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

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