Synopsis |
| 20 |
======== |
| 21 |
|
| 22 |
Multiple vulnerabilities in R could result in the execution of |
| 23 |
arbitrary code. |
| 24 |
|
| 25 |
Background |
| 26 |
========== |
| 27 |
|
| 28 |
R is a GPL licensed implementation of S, a language and environment for |
| 29 |
statistical computing and graphics. PCRE is a library providing |
| 30 |
functions for Perl-compatible regular expressions. |
| 31 |
|
| 32 |
Affected packages |
| 33 |
================= |
| 34 |
|
| 35 |
------------------------------------------------------------------- |
| 36 |
Package / Vulnerable / Unaffected |
| 37 |
------------------------------------------------------------------- |
| 38 |
1 dev-lang/R < 2.2.1-r1 >= 2.2.1-r1 |
| 39 |
|
| 40 |
Description |
| 41 |
=========== |
| 42 |
|
| 43 |
R includes a copy of PCRE which is vulnerable to multiple buffer |
| 44 |
overflows and memory corruptions vulnerabilities (GLSA 200711-30). |
| 45 |
|
| 46 |
Impact |
| 47 |
====== |
| 48 |
|
| 49 |
An attacker could entice a user to process specially crafted regular |
| 50 |
expressions with R, which could possibly lead to the execution of |
| 51 |
arbitrary code, a Denial of Service or the disclosure of sensitive |
| 52 |
information. |
| 53 |
|
| 54 |
Workaround |
| 55 |
========== |
| 56 |
|
| 57 |
There is no known workaround at this time. |
| 58 |
|
| 59 |
Resolution |
| 60 |
========== |
| 61 |
|
| 62 |
All R users should upgrade to the latest version: |
| 63 |
|
| 64 |
# emerge --sync |
| 65 |
# emerge --ask --oneshot --verbose ">=dev-lang/R-2.2.1-r1" |
| 66 |
|
