Synopsis
========

Roundup will make files owned by the user that it's running as
accessable to a remote attacker.

Background
==========

Roundup is a simple to use issue-tracking system with command-line,
web, and e-mail interfaces.

Affected packages
=================

    -------------------------------------------------------------------
     Package          /  Vulnerable  /                      Unaffected
    -------------------------------------------------------------------
  1  net-www/roundup      <= 0.6.4                            >= 0.7.6

Description
===========

Improper handling of a specially crafted URL allows access to the
server's filesystem, which could contain sensitive information.

Impact
======

An attacker could view files owned by the user running Roundup. This
will never be root however, as Roundup will not run as root.

Workaround
==========

There is no known workaround at this time. All users are encouraged to
upgrade to the latest available version of Roundup.

Resolution
==========

All Roundup users should upgrade to the latest version:

    # emerge sync

    # emerge -pv ">=net-www/roundup-0.7.6"
    # emerge ">=net-www/roundup-0.7.6"
