http://security.gentoo.org/

Severity:	normal
Title:	R: Multiple vulnerabilities
Date:	01/09/2008
Bugs:	#198976
ID:	200801-02

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	Architecture(s)
dev-lang/R	< 2.2.1-r1	>= 2.2.1-r1	All supported architectures

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"
