R is vulnerable to symlink attacks due to an insecure usage of temporary files.
|Package||dev-lang/R on all architectures|
|Affected versions||< 2.7.1|
|Unaffected versions||>= 2.7.1|
R is a GPL licensed implementation of S, a language and environment for statistical computing and graphics.
Dmitry E. Oboukhov reported that the "javareconf" script uses temporary files in an insecure manner.
A local attacker could exploit this vulnerability to overwrite arbitrary files with the privileges of the user running the application.
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-2.7.1"
