GLSA-200602-14 : noweb: Insecure temporary file creation

This script is Copyright (C) 2006-2014 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-200602-14
(noweb: Insecure temporary file creation)

Javier Fernandez-Sanguino has discovered that the lib/toascii.nw
and shell/roff.mm scripts insecurely create temporary files with
predictable filenames.

Impact :

A local attacker could create symbolic links in the temporary file
directory, pointing to a valid file somewhere on the filesystem. When
an affected script is called, this would result in the file being
overwritten with the rights of the user running the script.

Workaround :

There is no known workaround at this time.

Solution :

All noweb users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose '>=app-text/noweb-2.9-r5'

Risk factor :

Low / CVSS Base Score : 1.2
