R: Multiple vulnerabilities

R: Multiple vulnerabilities Multiple vulnerabilities in R could result in the execution of arbitrary code. R 2008-01-09 2008-01-09 198976 remote 2.2.1-r1 2.2.1-r1

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.

R includes a copy of PCRE which is vulnerable to multiple buffer overflows and memory corruptions vulnerabilities (GLSA 200711-30).

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.

There is no known workaround at this time.

All R users should upgrade to the latest version:


    # emerge --sync
    # emerge --ask --oneshot --verbose ">=dev-lang/R-2.2.1-r1"
