GLSA-200510-04 : Texinfo: 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-200510-04
(Texinfo: Insecure temporary file creation)

Frank Lichtenheld has discovered that the 'sort_offline()'
function in texindex insecurely creates temporary files with
predictable filenames.

Impact :

A local attacker could create symbolic links in the temporary
files directory, pointing to a valid file somewhere on the filesystem.
When texindex is executed, this 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 Texinfo users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose '>=sys-apps/texinfo-4.8-r1'

Risk factor :

Low / CVSS Base Score : 1.2
