Bugs: #112061
ID: 200511-19

Synopsis
========
eix has an insecure temporary file creation vulnerability, potentially
allowing a local user to overwrite arbitrary files.
Background
==========
eix is a small utility for searching ebuilds with indexing for fast
results.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 app-portage/eix lt; 0.5.0_pre2 gt;= 0.5.0_pre2
*gt;= 0.3.0-r2
Description
===========
Eric Romang discovered that eix creates a temporary file with a
predictable name. eix creates a temporary file in /tmp/eix.*.sync where
* is the process ID of the shell running eix.
Impact
======
A local attacker can watch the process list and determine the process
ID of the shell running eix while the "emerge --sync" command is
running, then create a link from the corresponding temporary file to a
system file, which would result in the file being overwritten with the
rights of the user running the application.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All eix users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose app-portage/eix
Availability
============
This GLSA and any updates to it are available for viewing at
the Gentoo Security Website:
http://security.gentoo.org/glsa/glsa-200511-19.xml

=========
Security is a primary focus of Gentoo Linux and ensuring the
confidentiality and security of our users machines is of utmost
importance to us. Any security concerns should be addressed to
