Synopsis
========

Portage may disclose sensitive information when updating configuration
files.

Background
==========

Portage is the default Gentoo package management system.

Affected packages
=================

    -------------------------------------------------------------------
     Package           /  Vulnerable  /                     Unaffected
    -------------------------------------------------------------------
  1  sys-apps/portage     < 2.1.3.11                       >= 2.1.3.11

Description
===========

Mike Frysinger reported that the "etc-update" utility uses temporary
files with the standard umask, which results in the files being
world-readable when merging configuration files in a default setup.

Impact
======

A local attacker could access sensitive information when configuration
files are being merged.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All Portage users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=sys-apps/portage-2.1.3.11"

References
==========
