GLSA-200411-13 : Portage, Gentoolkit: Temporary file vulnerabilities

This script is Copyright (C) 2004-2014 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-200411-13
(Portage, Gentoolkit: Temporary file vulnerabilities)

dispatch-conf and qpkg use predictable filenames for temporary files.

Impact :

A local attacker could create symbolic links in the temporary files
directory, pointing to a valid file somewhere on the filesystem. When
an affected script is called, this would result in the file to be
overwritten with the rights of the user running the dispatch-conf or
qpkg, which could be the root user.

Workaround :

There is no known workaround at this time.

# emerge --ask --oneshot --verbose '>=app-portage/gentoolkit-0.2.0_pre8-r1'
