Detail

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.

Description

The web interface plugin does not restrict access to the torrent upload functionality (CVE-2008-5905) and does not sanitize request parameters properly (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"
