GLSA-200511-19 : eix: Insecure temporary file creation

This script is Copyright (C) 2005-2014 Tenable Network Security, Inc.


Synopsis :

The remote Gentoo host is missing one or more security-related
patches.

Description :

The remote host is affected by the vulnerability described in GLSA-200511-19
(eix: Insecure temporary file creation)

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.

Solution :

All eix users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose app-portage/eix

Risk factor :

Medium / CVSS Base Score : 5.0
