GLSA-200509-21 : Hylafax: Insecure temporary file creation in xferfaxstats script

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-200509-21
(Hylafax: Insecure temporary file creation in xferfaxstats script)

Javier Fernandez-Sanguino has discovered that xferfaxstats cron script
supplied by Hylafax insecurely creates 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
the xferfaxstats script of Hylafax is executed, this would result in
the file being overwritten with the rights of the user running the
script, which typically is the root user.

Workaround :

There is no known workaround at this time.
