Synopsis
========
Multiple vulnerabilities in R could result in the execution of
arbitrary code.
Background
==========
R is a GPL licensed implementation of S, a language and environment for
statistical computing and graphics. PCRE is a library providing
functions for Perl-compatible regular expressions.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 dev-lang/R < 2.2.1-r1 >= 2.2.1-r1
Description
===========
R includes a copy of PCRE which is vulnerable to multiple buffer
overflows and memory corruptions vulnerabilities (GLSA 200711-30).
Impact
======
An attacker could entice a user to process specially crafted regular
expressions with R, which could possibly lead to the execution of
arbitrary code, a Denial of Service or the disclosure of sensitive
information.
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-2.2.1-r1"
