Synopsis
=======
Two vulnerabilities in the web interface plugin in KTorrent allow for
remote execution of code and arbitrary torrent uploads.

Background
=========
KTorrent is a BitTorrent program for KDE.

Affected packages
================
    -------------------------------------------------------------------
     Package           /  Vulnerable  /                     Unaffected
    -------------------------------------------------------------------
  1  net-p2p/ktorrent       < 2.2.8                           >= 2.2.8

Description
==========
The web interface plugin does not restrict access to the torrent upload
functionality (CVE-2008-5905) and does not sanitize request parametersproperly (CVE-2008-5906) .

Impact
=====
A remote attacker could send specially crafted parameters to the web
interface that would allow for arbitrary torrent uploads and remote
code execution with the privileges of the KTorrent process.

Workaround
=========
Disabling the web interface plugin will prevent exploitation of both
issues. Click "Plugins" in the configuration menu and uncheck the
checkbox left of "WebInterface", then apply the changes.

Resolution
=========
All KTorrent users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=net-p2p/ktorrent-2.2.8"
