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
==========
