Synopsis
=3D=3D=3D=3D=3D=3D=3D=3D

R is vulnerable to symlink attacks due to an insecure usage of
temporary files.

Background
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D

R is a GPL licensed implementation of S, a language and environment for
statistical computing and graphics.

Description
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D

Dmitry E. Oboukhov reported that the "javareconf" script uses temporary
files in an insecure manner.

Impact
=3D=3D=3D=3D=3D=3D

A local attacker could exploit this vulnerability to overwrite
arbitrary files with the privileges of the user running the
application.

Workaround
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D

There is no known workaround at this time.

Resolution
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D

All R users should upgrade to the latest version:

      # emerge --sync
      # emerge --ask --oneshot --verbose ">=3Ddev-lang/R-2.7.1"
