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"

=========
