Multiple vulnerabilities in R could result in the execution of arbitrary code.
|Package||dev-lang/R on all architectures|
|Affected versions||< 2.2.1-r1|
|Unaffected versions||>= 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"
